Emeka?.

Thank you, Sandy. Good afternoon, everyone. For Q4 fiscal 2017, GAAP net sales were $140 million, an increase of 2% sequentially and 18% year-over-year. Q4 GAAP net sales included $1.7 million expense for the Comcast warrants.

Fiscal 2017 GAAP net sales increased 11% over fiscal 2016 to $544.3 million, and included a total of $5.4 million from Comcast warrants. Q4 GAAP gross margin increased 50 basis points sequentially to 59.6% due to the impact of lower sequential Comcast warrant expense and a more favorable mix.

Q4 GAAP operating expense increased approximately 63% sequentially due mainly to the non-recurrence of the gain from the Snowbush divestiture, and the bad debt charge in Q3, slightly offset by the impact of higher stock price and equity compensation. Q4 GAAP tax rate was approximately 27.1% compared to 15.7% in Q3.

Q3 benefited from a more favorable tax rate as a result of the Snowbush divestiture. For fiscal 2018, we expect our GAAP tax rate to be in the 23% to 27% range.

Moving on to the non-GAAP results, which exclude the impact of equity-based compensation, amortization of acquired intangibles, acquisition of disposition-related and other non-recurring charges, not tied to current operations.

Q4 fiscal 2017 net sales were $141.8 million, a 1% sequential increase and 20% increase over Q4 fiscal 2016 and represented the fifth consecutive quarter of results above the mid-point of our guidance. Fiscal year 2017 net sales were $549.7 million, an increase of 12% over the prior year.

In Q4, shipments into Asia represented 76% of total sales, North America was 17% and Europe represented 7%. Total net sales to distribution represented approximately 69% and direct sales represented approximately 31%. Q4 bookings increased sequentially and year-over-year, and resulted in a book-to-bill firmly above 1.

Total bookings accounted for approximately 44% of shipments during the quarter. Q4 non-GAAP gross margin was 60.5%, an increase of 10 basis points sequentially due to more favorable mix. We expect Q1 fiscal 2018 non-GAAP gross margin to be flattish sequentially as higher absorption due to stronger demand is offset by less favorable mix.

Going forward, we expect that higher revenue from our optical transceiver and lower products, increased absorption from overall revenue growth and royalty and licensing revenue from LoRa, will enable us to sustain and expand our gross margins from current levels.

As a result, we are including our non-GAAP gross margin target range to 58% to 63% versus our prior range of 55% to 60%. We expect most of this increase in gross profit to flow-down to earnings as we maintain a very tight control over operating expenses.

Accordingly, we are also increasing our non-GAAP operating model to 28% to 32% from the current 25% to 30%. We expect to achieve the midpoint of this new range of 30% at a quarterly revenue run-rate of approximately $185 million.

Q4 non-GAAP operating expense was $52.2 million, up slightly from Q3 levels due to higher new product expenses, offset by the bad debt charge in Q3. In Q1, we expect non-GAAP operating expense to decrease approximately 2% sequentially, mainly from lower new product expenses.

For modeling purposes, as we highlighted in our last earnings call, we expect our non-GAAP operating expenses for fiscal 2018 to be similar to fiscal 2017 levels, and to average of approximately $52 million a quarter. Q4 fiscal 2017 non-GAAP tax rate was approximately 20%.

We expect our fiscal 2018 non-GAAP tax rate to fall between 20% and 24% due to higher income from high tax jurisdictions. In Q4, cash flow from operations was approximately $33 million. For fiscal 2017 in line with revenue growth, cash flow from operations increased 15% sequentially to $118 million or approximately 22% of revenue.

During Q4, we purchased our office building in Burlington and Canada for approximately $12 million. And net several more strategic investments in several companies to gain access to technologies and further develop the lower ecosystem.

Cash and investments in Q4 were $297 million and our debt balance at the end of Q4 was approximately $243 million, leaving out in a $54 million positive net cash position. In Q4, approximately 75% of our cash and investments were domicile and international accounts, and 25% was based in the U.S.

We repurchased $0.5 million of stock, and the outstanding stock repurchase authorization is approximately $62 million. The primary use of cash continues to pay down our debt, repurchase our shares, and make strategic investments.

In Q4, accounts receivable decreased 14% sequentially due to better shipment linearity and higher mix of shipments to distributors. Our days of sales outstanding decreased 2 days to 36 days, and remains below the target range of 40 to 45 days.

Net inventory in absolute dollar terms increased approximately 5% sequentially, and represented 104 days of inventory, slightly above the target range of 90 to 100 days. In Q1, we expect our inventory to increase on both an absolute dollar amount and days of inventory to address increasing demand. In summary, fiscal 2017 was a great year for Semtech.

We returned to growth as all of our businesses performed well. We maintained our gross margin above our target range, which we believe is sustainable, going forward. Our spending discipline allowed us to grow earnings 5 times faster than revenue, with our growth engines expected to gain further momentum and leverage in a new operating model.

We believe the Company is poised to deliver a record financial performance in fiscal 2018. I will now hand the call over to Mohan..

Thank you, Emeka. Good afternoon, everyone. I will discuss our Q4 fiscal year 2017 performance by end of market, and by product group, discuss our fiscal year 2017 performance, and then provide our outlook for Q1 of fiscal year 2018.

In Q4 of fiscal year 2017, we achieved non-GAAP net revenues of $141.8 million, an increase of 1% sequentially and an increase of 20% over Q4 of fiscal year 2016. End-of-market demand increased from the enterprise computing, communications and industrial end markets, and decreased from the high-end consumer end market.

For Q4 of fiscal year 2017, we posted non-GAAP gross margin of 60.5% and non-GAAP earnings per diluted share of $0.37. In Q4 of fiscal year 2017, net sales from the enterprise computing end market increased nicely over the prior quarter, and represented 30% of total net revenues.

The industrial end market also increased over the prior quarter and represented 26% of total net revenues. The high-end consumer end market decreased from the prior quarter, and represented 26% of total net revenues.

Approximately 20% of high-end consumer net revenues were attributable to mobile devices and approximately 6% were attributable to other consumer systems. Finally, net revenues from the communications end market increased over the prior quarter and represented 18% of total net revenues. I will now discuss the performance of each of our product groups.

In Q4 of fiscal year 2017, our Signal Integrity Product Group delivered strong results, increasing 7% sequentially and 12% over the same period a year ago, and represented 46% of total net revenues.

Enterprise computing and communications end market demand grew sequentially, led by record quarterly demand from our cloud and hyperscale data center customers, and the expected recovery from our PON and wireless base station customers. Revenues from the industrial end market remained flat.

Semtech's industry-leading cloud data recovery platforms, or CDRs, and physical media devices, or PMDs, are used in a wide range of optical modules from 1 gigabit per second to 100 gigabit per second that go into the data center, PON and wireless base station markets.

We expect these three markets to continue to grow over the next few years, and move to higher data rates. These higher data rates drive the need for increased Signal Integrity, resulting in the increased adoption of Semtech's leadership CDRs.

Use of CDRs in higher-speed 100 gigabit per second optical modules being deployed in cloud and hyperscale data centers is resulting in very strong growth for Semtech single channel and quad channel 25 gigabit per second CDR platforms. Our CDR business achieved a record performance in FY17.

We expect the trend for higher data rates to continue, and result in another record revenue performance from our CDR platforms in FY '18. We also made further progress toward the introduction of our high-performance single-lambda 100 gigabit per second PAM4 platform, expected to sample this year.

This platform, which incorporates the DSP solutions from our investment in MultiPhy, is progressing well and feedback from our Tier 1 strategic engagements continues to be very positive.

With the rollout of this solution, we expect to gain a strong position in the emerging 100-gigabit per second single-lambda optical market and the 400-gigabit per second optical market for cloud and hyperscale data center solutions that are expected to ramp in fiscal year 2019.

In FY17, we also saw record revenues for our PMD platforms, which include TIAs and laser drivers used in PON systems and base stations.

Strong demand for our new 10-gigabit per second PON products is enabling our customers to upgrade their PON systems from 2.5G PON to 10G PON; our base station customers are also increasing their backhaul data rates, and we expect this trend as well as the PON data rate increase, to contribute to further growth from our PMD business in FY18.

Semtech's leadership position in the optical connectivity market is the result of our continued focus and investment in new platforms that deliver the highest performance and integration at the lowest power consumption in the industry.

We believe these attributes position our Signal Integrity Product Group to continue its double-digit revenue growth, which it has produced over the last five years, and follow its record FY17 with another record year in FY18.

For Q1 of fiscal year 2018, we expect net revenues from our Signal Integrity Product group to increase nicely, led by continued growth in demand from the data center, wireless base station and PON markets. Moving on to our Protection Product Group.

Our Protection Product Group delivered solid results, growing 3% sequentially and 25% over the same period a year ago, and represented 29% of total net revenues. Stronger demand from our communications and industrial end markets offset seasonally lower demand from our high-end consumer market.

Q4 results marked the third consecutive quarter of sequential growth for our Protection Product Group. The increasing diversification of our protection business is very encouraging as we expand our footprint into a broader range of end markets, and we penetrate a broader set of mobile customers.

In Q4 of fiscal year 2017, demand from our China smartphone customers increased sequentially and exceeded the quarterly net revenues from our Korean smartphone customers for the first time in our history.

Demand at our Korean smartphone customers declined sequentially due to customary and year-end inventory reduction efforts and the cancellation of Samsung's Note 7 platform that was previously announced. Our Protection Product Group has focused on developing solutions to address an increasingly diverse array of applications and vertical markets.

During Q4, we expanded our Z portfolio with the RClamp0561Z, targeted at ultrahigh-speed data interfaces, including USB 3.1 and 10-gigabit per second Ethernet, used in next generation mobile and computing systems.

In FY '17, our Protection Product Group grew 8% over the prior year as we saw our penetration of China smartphones increase, and our penetration of non-smartphone markets also increase.

Our protection business continues to diversify nicely as we see increasing opportunities for advanced protection from the automotive, IoT and communication infrastructure segments.

The advanced lithographies used in leading systems today requires the most advanced protection platforms, and Semtech continues to deliver the industry's highest performance protection platforms.

We believe our strategy of focusing on advanced lithography protection and high-speed interfaces across multiple vertical markets should continue to pay off and help drive our Protection Product Group to another growth year in FY '18.

In Q1 of fiscal year 2018, we expect our protection business to increase, driven by growth in demand from the high-end consumer market. Turning to our Wireless and Sensing product group.

In Q4 of fiscal year 2017, net revenues from our Wireless and Sensing product group decreased 12% sequentially but increased 34% over the same period a year ago, and represented 15% of total net revenues.

Higher demand from the industrial end market, led by our LoRa-related platforms, was offset by seasonally lower demand for our proximity sensing platforms from the high-end consumer market. LoRa continues to exceed our highest expectations and is rapidly emerging as the low-power wide-area network, or LPWAN, technology of choice in the industry.

LoRa enables the rapid build-out of low-cost, low-power secure wide-area networks that provides IoT data for cloud-based data analytics reporting and control. LoRa enables many IoT applications to be transformed from a concept to a reality due to the long-range, low-power and low cost of a LoRa sensor node.

In fiscal year 2017, our Wireless and Sensing product group achieved record revenues. Semtech's LoRa-related revenue nearly doubled from the prior year to achieve record levels, and we expect it to double again in FY18, and represent $100 million of revenue within the next two years.

In FY17, Semtech, along with its LoRa Alliance partners, announced many significant LoRa-related accomplishments and milestones.

Some of the most significant milestones in FY '17 included; LoRaWAN network trials were announced or in some stage of deployment in more than 50 countries worldwide, including China, Japan, Korea, Taiwan, United States, India, France, Belgium, New Zealand and Ireland; with large globally recognized service providers that include Comcast, SoftBank, SKT, NTT, Orange, Boyd and Tata.

We continue to expect the most, if not all, major regions of the world will have some form of LoRaWAN network deployed, or in the midst of deployment by the end of calendar year 2017.

LoRa Alliance membership more than doubled from the end of fiscal year '16, and now exceeds over 450 members worldwide and includes companies addressing all areas of the LoRa ecosystem from sensors, gateways, and network operators to cloud-based analytics and software companies.

Semtech's GPS-free LoRa geolocation capability was successfully launched, and we have signed four agreements with several in the pipeline.

Our GPS-free geolocation capability allows IoT operators to add asset-tracking and geolocation of any LoRaWAN sensor operating over a LoRaWAN network, creating additional revenue opportunities for service providers and Semtech. Semtech introduced and demonstrated at CES in January its LoRaWAN picocell gateway reference design.

This platform enables consumers and small enterprises to create their own private LoRaWAN network at very low cost, making it perfect for smart building, smart enterprise and smart campus environments. The LoRa picocell opens up numerous new applications that require low-cost, long-range, low-power and dense connectivity.

Finally, in FY '17, we signed a strategic deal with Comcast to partner with them to trial LoRaWAN networks in the USA. The agreement provides Comcast with a Semtech warrant at best, based on the rollout of the Comcast LoRaWAN network.

Currently, Comcast trial is on schedule with LoRaWAN coverage in two major cities, and a number of verticals defined to form the basis of their POC. Comcast also announced their machineQ IoT platform to enable customers to build IoT strategies, utilizing Comcast LoRaWAN network and services.

It is still early, but we believe that the progress to-date since the signing of our agreement has been very positive. We expect that by the end of this fiscal year, that three of the five milestones will be completed, which will provide the LoRaWAN coverage in 10 major cities in the U.S.

We also believe that Semtech and our LoRa Alliance partners are beginning to establish LoRa as the de facto standard for global LPWAN IoT deployments in what we think could be a multibillion-dollar industry within five years.

In Q4 of fiscal year 2017, demand for our proximity sensing platforms decreased seasonally from the prior quarter's record performance, but increased over the same period a year ago. Our sensing platforms continue to win designs in tablets, smartphones and wearables across all regions.

As radio transmission power increases in mobile systems, we expect the adoption of Semtech's proximity sensing platforms to increase to enable system compliance with regional regulations. In FY '17, our proximity sensing revenues achieved record revenues, and we anticipate that FY '18 revenues will also achieve record levels.

For Q1 of fiscal year 2018, we expect net revenues from our Wireless and Sensing product group to increase significantly, driven by both our LoRa and proximity sensing businesses. Turning to our Power and High-Rel Product Group.

In Q4 of fiscal year 2017, our Power and High-Rel Product Group declined 13% sequentially due to seasonality, but increased 23% over the same period last year and represented 10% of total net revenues.

Demand from our enterprise computing end market increased, while demand from our high-end consumer, communications and industrial end markets decreased. Our Power and High-Rel business remains focused on delivering differentiated platforms for the automotive, industrial and wearable segments.

Semtech's wireless charging platforms deliver flexibility and versatility by offering a programmable, multimode and scalable power range from 100 milliwatts to over 40 watts. The flexibility and programmability of this platform allows customers to rapidly update their charging systems as industry standards evolve.

Customer interest and design wins for our wireless charging platform remains solid. In Q4, we announced several additions to Semtech's LinkCharge wireless charging platform. This family of wireless power products provides a range of solutions that target next-generation charging systems for consumer infrastructure and industrial applications.

The family includes the LinkCharge 40 Series for 40-watt applications, the LinkCharge 20 Series for 20-watt applications and the LinkCharge CT for countertop and general industrial charging applications.

This platform is compatible with all the major industry standards, ensuring that future mobile devices can potentially be charged from a single transmitter platform.

The demand for wireless charging capability is expected to increase significantly over the next five years, as larger feature-rich and power-hungry mobile devices, will need to be charged several times per day in different locations at different times without the need for cables.

Our Neo-Iso switching platform enjoyed another solid quarter in Q4 FY17, and we have seen real customer interest in this platform, targeted at smart thermostat, alarm panels and factory automation systems. Our Neo-Iso platforms allow customers to update and replace designs that we use in older mechanical relays with smarter solid-state technologies.

In Q1 of fiscal year 2018, we expect our Power and High-Reliability Product Group to decline slightly. In Q4, the total Company distribution POS achieved a new quarterly record, increasing 6% from the prior quarter.

Distributor inventory in Q4 increased by 1 day to 71 days, up from 70 days in Q3 of fiscal year 2017, and remains at the lower end of our 70 to 80-day channel inventory model.

Our distributor business remains balanced with 56% of the total POS coming from high-end consumer and enterprise computing end markets, and 44% of total POS coming from industrial and communications end markets. Moving on to new products and design wins. In Q4 of fiscal year 2017, we released 27 new products and we achieved 2,026 new design wins.

Now, let me comment on our fiscal year 2017 performance. In fiscal year 2017, Semtech returned to growth with total non-GAAP net revenues increasing 12% over fiscal year 2016 to approximately $550 million. In addition, our non-GAAP earnings per share increased 60% over FY16 to $1.38.

Our Signal Integrity Product Group grew 15% over FY16 to achieve record revenues, driven by record CDR revenues and record PMD revenues. Our Wireless and Sensing Product Group grew 15% over FY '16 and also achieved record revenues, driven by record LoRa and record proximity sensing revenues.

Both product groups are expected to have double-digit growth and achieve record revenues again in FY18. In FY17, our Protection Product Group grew 8%, which was the first annual increase in two years, and we expect FY '18 to be another high single-digit growth year for our Protection Product Group.

Finally, our Power and High-Rel Product Group also grew 7% versus FY16, and we expect this product group to also grow in FY18. In FY17, we continue to defocus or divest non-strategic businesses, including our Snowbush IP business and our timing and synchronization business.

We also executed on a number of strategic minority investments, including MultiPhy and MyDevices, which help position us to drive future growth in our target market segments.

Other significant achievements in FY17 included maintaining our non-GAAP gross margins above the high end of our 55% to 60% target range, and managing our OpEx to drive non-GAAP earnings growth at 5 times the rate of our non-GAAP net revenue growth.

We achieved 7,794 design wins, 88 new product releases, and generated $118 million of cash from operations. We are pleased with our return to growth and the tremendous momentum we have from our product groups in several of the industry's fastest-growing and exciting end markets.

Our increasingly diversified product portfolio, balanced end markets and diverse customer base, position Semtech very well to continue outperforming our peer group and industry in FY18. Now, let me discuss our outlook for the first quarter of 2018.

Based on the strength of recent bookings trends and our backlog entering the quarter, we are currently estimating Q1 non-GAAP net revenues to be between $142 million and $150 million. To attain the midpoint of our non-GAAP guidance range, or approximately $146 million, we needed net terms orders of approximately 34% at the beginning of Q1.

We expect our Q1 non-GAAP earnings to be between $0.39 and $0.43 per diluted share. I will now hand the call back to the operator. And Sandy, Emeka and I will be happy to answer any questions.

Operator?.

Certainly [Operator Instructions]. Your first question comes from the line of Craig A. Ellis with B. Riley Financials. Craig, your line is open..

Thanks. Well, that sounded so official. Congratulations on the nice execution guys and what looks like very broad-based growth in the product portfolio, Mohan. The first question is a follow-up on the increase in the intermediate-term gross margin model.

You mentioned that one of the factors causing the increase was the expected contribution from licensing and royalty.

Can you provide more color on when you would expect those to be material? And the degree to which they contributed to, what looks like a 300 basis point increase, at the midpoint?.

So, if you recall during the Analyst Day that we held in June of 2016, we basically talked about the geolocation revenue and its potential to help us drive our gross margins up. So when you look at the gross margins, the increase in the target range, there are three key drivers; the first one is the mix.

As Mohan in his prepared remarks has talked about all the growth engines that we have; unfortunately for us, most of our growth engines are coming in with gross margins that are higher than our current levels. So, as we continue to see a ramp in those, we would expect that to drive to gross margin expansion.

The second thing that is driving the gross margin, the increase in the target range, is just the overall business being higher, driving a much more increase in manufacturing activities and hence, higher absorption. And the third key driver, like you mentioned, is the license and the royalty from LoRa.

As we said during our Analyst Day, back in June, we expect that the licensing and the royalty is probably still more of two to three-year uplift for it to get to a significant size, but we're very pleased with what we're seeing so far.

Right now, it is not contributing that much, but we do expect that in two or three years we should see a significant contribution for that.

So the way I would expect to see us achieving this target is that in the next one to two years, driven by the higher mix of higher gross margin products and the increased absorption, I would expect that to take us to about 61%-62% range, and then in the next two to three years, that the licensing will take us to the high end of the new target range..

And then, the follow-up question, I'll flip it over to Mohan. Mohan, in talking about the product line dynamics, you talked about wireless charging. That's been a market where we've been waiting for some large players to move ahead with device and wireless charging. It looks like that may be happening.

What's the sense you're getting from customers on the transmit side and building out all the points that would assist your businesses as you put the scale of wireless charging?.

Craig, what we see is generally a movement towards more wireless charging across the industry; wearable, increases in wearables, is generally driving it; mobile devices, but even higher power industrial equipments and power drills and those type of things, as well as automotive, driving the need for more wireless charging functions.

Obviously, if the major mobile companies integrate wireless charging into their devices, it does help stimulate and catalyze the industry somewhat. But the beauty about our solutions and our approach is that we're not tied to one standard, we have programmability in the products. And so, rapid changing of the functionality is possible.

And so customers are moving with our solution, I think, can provide a pretty quick solution to customers who do come out with -- and devices with wireless charging..

And then final question and then I'll jump back in the queue. Emeka, I believe the target margin range was predicated on $180 million in sales, but that, I think, annualizes to something around 770, if I got that right.

But, it looks like what the Company is also saying with the intermediate-term model and the revenue basis for that model is that it's moving towards its $1 billion in annual sales goal.

Is that the way we should read that? And what are some of the gives and takes as you look out more towards the longer term to get to that longer-term target that you have for the Company?.

So, I think I’ve just took you through the gross margin expansion, which, obviously, is starting to be a key driver to achieving the operating margin target.

I think on the other hand, what you probably in terms of modeling, probably just need to look at it like what we tried to target is to see operating expenses, maybe grow it at about half the rate of our revenue growth.

So, yes, as I look out and see how do we play out of it, I'm assuming the $1 billion revenue target is definitely achievable within the next three, four, five years.

And I'm not sure that there is really anything else that is really going to be in terms of puts and takes, I think the two key things are over there is going to be the gross margin expansion and the fact that operating expenses are beyond our control..

Your next question comes from the line of Harsh Kumar with the Stephens, Inc. Harsh your line is open..

I have a couple of questions, Emeka, one for you. Your OpEx was pretty well controlled. It looks like it's going to be pretty well-controlled. It looks like, if your guidance shapes out for the April as you've guided it.

I was curious how much revenue can you do without you have to seriously look to expand revenue from current levels? In other words, how much revenue leverage is possible at current levels of revenue, current levels of OpEx?.

So, at this point Harsh, the new models definitely assume that we are growing organically. I think we've been talking about this that even in the last two years where we were going through our difficulties. One of the things that we did was we kept our eyes on the future. We continue to take care of our operating expenses.

But even though we were bringing them down, we were sure to ensure that we had everything, we left everything in the Company that we actually need to achieve the $1 billion of revenue target. So I think the operating expenses we have right now is definitely the infrastructure we have.

Everything that we have in the Company is all been sized up and poised to support the $1 billion of revenue. And like I mentioned to Craig, I would expect to see operating expenses maybe growing at about half the rate of revenue growth, and that's how we expect to get to the new model and to get to the high end of that model..

And then maybe, Emeka one more for you is if I look at your guidance on the top line on April, for April versus maybe where the street was. And maybe just even looking at how well you are growing in April, which, theoretically, should be seasonally down quarter.

So, how much of that is a function of the Samsung ramp? Because we've heard the Samsung phones coming out at the end of March and you're probably going to benefit dramatically, or to some degree from it? And then also, part two of the question is, what else is growing in this April quarter, because in my opinion it's somewhat unseasonal.

And then how should we think about seasonality for your business anymore with all these growing ties?.

So Harsh, I think first of all, let me comment on the growth in Q1. Certainly, our Signal Integrity Product Group is going to grow nicely in the quarter. We have data center growing nicely for us, that market is doing very well. I also mentioned that PON and base stations are recovering a little bit in Q1, so that's good.

You have protection growing in Q1, but we've been somewhat modest in our thinking about Samsung's strength and where they could do well. And I think the timing of that is going to be end of Q1 maybe more Q2, and certainly Q3 time frame. So for Q1, I think, it's a combination of the Signal Integrity products, some protection.

But also, our Wireless and Sensing is doing incredibly well. Obviously, LoRa is growing very nicely, and our proximity sensing is doing quite well across different mobile platforms; some of them -- some high-profile platforms, but also in some customers that we haven't historically penetrated with our proximity sensing.

So, in general, I would say, it's pretty broad based our strength..

And then could you address maybe how we should look at seasonality for the next year or two years for you guys, with all these fast growing parts? Or is there even….

Yes, it's a little bit challenging, because something like LoRa, we're not quite sure about the seasonality there. But I would say, for now, I think we expect the first half to be quite strong and the second half, depending on the consumer business, particularly the Q3 time frame, I think to be perhaps a little bit weaker.

But its early days, Harsh, and it is tough for us to really comment on the seasonality, given that we've got so many secular things going on..

And my last one and then I'll move back in the line. Would you, Mohan, give us some kind of an idea of Comcast implementation in the two cities? How it's going? And finally, when can we expect client devices? I know there's a lot of infrastructure stuff in LoRa right now..

Well, actually, the end devices now are starting to ramp up quite nicely. So, we have gateways being deployed across the world, which was our strategy. And now we have end devices that are now connecting to those gateways. So it's actually a very nice path that's being followed. So, with Comcast specifically, I think the progress is very good.

They have two cities covered as per the agreement. And so, now they are running proof of concepts with attachments to those gateways in those cities and proving out some verticals and the progress is good. I can't really comment specific details about what they're doing and how they're doing it. But I can tell you that the progress is good.

And as I mentioned in my script that the anticipation is that, by the end of the year, the milestone, the third milestone which covers 10 cities, will be achieved. And so, that's a good positive sign, I think..

Your next question comes from the line of Rick Schafer with Oppenheimer. Rick, your line is open..

Maybe I'll just follow-up on the protection question for a second. I know it was up nicely again this quarter. What would growth have been, I guess, without the Note 7 headwind? And would that be an indication of what we can look for, for expected growth rates? And maybe as part of that answer.

I mean, do you see a scenario where growth actually accelerates from here with the move to smaller lithographies?.

So in Q4, Rick, we had mentioned that on our previous call that it was about $4 million per quarter impact to us. So, you could add $4 million essentially to our Q4 number, that's what the number would have been, and the Note 7 not been canceled.

Now, having said that, it's difficult to say because they, I think, Samsung is still very aggressive in trying to win market share. And they would maybe replace some of the Note 7 phones with other phones. And so, it's difficult to call. As you know, they are expecting to release some new phones this year, and we expect them to do quite well.

But one of the things we have done nicely, I think, is to diversify. So we are exposed to China smartphones, as well as Korean smartphones and as well as other mobile devices. And I think a high single-digit growth rate for this business is a good number to plan on..

And then maybe a follow-up on LoRa then as well.

Could you give any color on current revenue distribution by region or by customer? Are you more concentrated in Europe with a few customers there? And maybe, how does that look over the next year or two as some of the new cities, like in North America for instance, start to ramp?.

So, the way we look at it, Rick, is that we look at infrastructure first. Once the gateways are in place, it means that end nodes are going to follow once the vertical solutions are in place. And so, our whole approach is being, let's get as many gateways deployed, and these are public and private networks.

And with our new picocell gateway, even consumer-based applications; I would say, Asia is in the lead that includes Korea and China and Taiwan; I would say, Europe is on par, probably a little bit behind in terms of actual full deployments.

But it's a little bit more fragmented with the countries, different countries; some countries are doing better than others. USA, obviously, you look in terms of Comcast, but I think in Comcast can catch up very quickly and U.S. can catch up very quickly. Even outside Comcast, we have a lot of activity, more on the private networking side in the U.S.

So I think the U.S. is starting to move quite nicely for us. And then when the gateway is deployed, I think it's going to be -- you're going to start hearing us, hearing from us, talking about attach rates. And attach rates to different gateways and what we expect from this region. So I think more to come.

Its early days to do that now, but I would say that probably by mid-year, we'll be starting to talk about that..

And maybe early days for this question then too. But I mean, if you look out at a couple of years from now, when you're at $100 million in LoRa revenues.

Would you hazard to guess what percent of those revenues would be license and royalty looking out those two years from now?.

I think it will be quite small at that time. Because so the way to think about geolocation, you need the gateways and then you need the end nodes and then the geolocation service on top of that. So we had anticipated.

And we're starting to get small revenues now, but I think the three year time frame is more the time frame where we'll start to see the geoloc revenues really start to ramp up. That could change. Lot of these use cases that are emerging are new markets.

I mean there really are new applications that are opening up for using LoRa for LPWAN connectivity; and some of them are quite compelling that could generate much faster geolocation revenue. But at this point, I would say, it's probably closer to the two to three years out..

Your next question comes from the line of Steve Smigie with Raymond James and Associates. Steve, your line is open..

This is Vince Celentano on for Steve. I just want to also congratulations on the strong quarter and guide; also great job with the diversification efforts in the handset space with the Chinese OEMs.

I was wondering, what kind of content expansion do you expect for the Chinese handsets in 2017? In general, do you expect revenue growth to come from more of getting traction in new OEMs? Or is it more about getting more of your content on your existing customers?.

So initially, if I look at it, the China -- China is a new -- China smartphones anyways is really a new opportunity for us that we've been working for over the last year or so. And now we're starting to see really good traction on. But historically our penetration of the mobile market has been with protection devices.

And now we're starting to see revenues from both protection and proximity sensing devices. So, yes, that content increases. It's not dramatic increase, but I would say, it's an increase. And then a lot depends on which phones are using the proximity sensing and protection devices. Not all the phones will use proximity sensing.

Some of the regions don't have the regulations yet in place, so some customers don't ship into those regions where they have the important compliance requirements. So it varies. But I would say our content is increasing and our expansion into China phones is also increasing..

And then switching over to the data center, since you’re really seeing opportunity for you guys, especially as you transition over to that single-lambda; as of right now, but for 100G specifically.

How much of the total debt in our revenue would you say was that last year? And what are you targeting for this fiscal year as far as100G sales?.

Well, 100G -- so first of all, let me clarify that it's not single-lambda it's quad 25-gig at the moment, and that's what we see as being the predominant revenue driver for the next couple of years. 100-gig single-lambda, we see as FY19 story. And it's ramping very fast, and this past year, it ramped up very fast.

I would say, now, it's about equal percentage relative to the other bandwidths that are being shipped..

Your next question comes from the line of Mitch Steves with RBC Capital Markets. Mitch, your line is open..

I just had a few one on the LoRa product portfolio. I think we're trying to do the math, just trying to figure out what the run rate is. But I thought that it was supposed to be in the industrial segment, but then you stated that the industrial segment was flattish year-over-year.

I'm just trying to reconcile the point where LoRa fits in the entire, both the end market side and the product segment side?.

We have our LoRa revenues in the industrial segment, Mitch. And so, if industrial came down it was probably as a result of one of the other businesses coming down, not LoRa..

And then from the product segment side, it's all the LoRa revenue, it's actually Wireless and Sensing and timing?.

Yes, correct..

So we should basically try to back into the math on the industrial side of what the wireless side of that, so it kind of implies you do maybe $10 million a quarter now on LoRa?.

No, LoRa revenue is closer to the $20 million to $30 million range in FY17. And we're expecting that to double to close to somewhere between $40 million and $60 million in FY18. And then as we said to get to $100 million in FY19 is the goal. That's always been the two goals.

The revenues come from a contribution of gateway revenue, chips from gateway revenue and chips from end node devices. So, the momentum is very good there..

Your next question comes from the line from Cody Acree with Drexel Hamilton. Cody, your line is open..

Maybe Mohan, could you just go back and summarize quickly your thoughts on the in-segment growth rates for 2018, you interspersed as, I think, in your prepared remarks. But if you could just summarize those….

For the product groups, I would say, our Signal Integrity Product Group, we expect double-digit growth; I would say Wireless and Sensing we expect double-digit growth; Protection, high-single-digits and Power and Hhigh-Rel low to mid-single-digits..

And Emeka, you gave some delineations, some breakdown of the drivers of your gross and operating margin improvements.

Can you really just talk about linearity of how you expect to get there? How -- does it sound like the royalty revenues are going to be that big of a contributor in the near-term? So, just how should we think about the acceleration of these market trends?.

So Cody as you can imagine a bulk of our gross margin and the expansion that I'm talking about is going to be driven by mix. So, it's always very difficult to talk about the linearity of when you're talking about mix.

But I think what I tried to say in an earlier response was that, I would expect that given the current mix improvements that we are expecting from our optical transceiver products and LoRa and just the higher levels of manufacturing activity, that that should allow us to maybe get to the 61%, 62% in the next one to two years and then for the location revenue, the geo-location [indiscernible] and royalty to take us to the high end about three years time..

And then, lastly, I guess, Mohan, could you just talk about the success that you have had with diversification and protection with the Chinese OEMs? Maybe you can single out or any places that you're particularly serve?.

Well, we've been looking to China smartphone angle and China Mobile angle for, as I said, quite a while now maybe last couple of years. And done a very good job and I think had very good success, both with our protection and our proximity sensing devices.

There are a number of China Mobile manufacturers, and we are fortunate to have relationships with a couple of them that are doing very well. I think that they will continue to do well. And our feeling is it's a nice balance to have. Obviously, we have success with Korea. We have success in China now. We've always had some success in the U.S.

market, not as much as we maybe would like. And there is an opportunity there in the future. But it does help us to have multiple customers now that are contributing to the business versus just historically from Korea..

I guess, maybe another way.

Is there any of the leading Chinese OEMs that you're not working with?.

No..

Your next question comes from the line of Lena Zhang with Summit Redstone. Lena, your line is open..

Most of my questions have been answered, just one on the foundry supply.

Have you noticed supply delivery time or stretch and recent delay?.

Well, I think, Lena, it depends area-to-area which segment we're in. But supply is tight, it's not like there's a lot of capacity out there. So, that is healthy sign for the industry. Demand is strong.

And so when demand is strong and supply is tight, one has to be very cautious about making sure you have right balance in place and you're forecasting mix correctly, and those types of things. But it does vary from segment-to-segment. Obviously, the segments that we are most concerned about are the high volume segments, like the consumer segments.

And at the moment, I think, there's capacity there. But if the mobile customers start to ramp up successfully in Q2 and Q3 and then sell phones successfully then obviously that's going to put a lot of pressure on the supply chain..

There are no further questions, at this time. I will turn the call back over to the presenters..

Thank you. In closing, fiscal year 2017 was an exciting year with faster growth and outperformance at Semtech has become accustom to in the last 10 years. We outperformed our peers and industry while leading the industry to several of the fastest-growing segments of the industry.

We are off to a solid start in FY18, and are expecting several of our product groups to achieve record results in FY18 and beyond. And help drive the Company along its positive path of getting to $1 billion in net revenues.

In addition, due to the confidence we have in our current strategy and our operational performance, we are increasing both our non-GAAP gross margin model range and our non-GAAP operating margin model range. With that, we appreciate your continued support of Semtech, and look forward to updating you on next quarter. Thank you..

Thank you. Ladies and gentlemen, this concludes today's conference call. You may now disconnect..
