Semtech Announces ToPSync Product Platform

Semtech - Semtech Corporation Terry Sears, (805) 480-2052 This e-mail address is being protected from spambots. You need JavaScript enabled to view it Semtech Corp. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the expansion of its ToPSync(TM) product platform with the availability of the ACS9593, an IEEE1588v2 precision time protocol (PTP) slave device that is a cost-effective, high-precision time synchronization solution for deployment in wireless base stations.

The ACS9593 device provides time recovery and delivery to networking equipment in wireless base stations used in 3G, 4G, WiMAX and Long Term Evolution (LTE) networks. The highly precise device delivers time alignment performance better than +/-2 us and frequency alignment performance better than +/-10 ppb when measured on a managed five-switch Gigabit Ethernet network under G.8261 test conditions. Previously this level of accuracy could only be achieved through the use of highly accurate and costly combinations of GPS modules and oscillators.

With the ACS9593, carriers can deploy wireless femtocells and pico base stations in large office buildings, apartment complexes and on campuses to improve coverage, and use an IP network to connect them cost-effectively to a central switch. Before ToPSync(TM) commercial availability, providing synchronization meant using a GPS-based solution, which required costly building retrofits to provide line of sight to the satellite and the use of an expensive oscillator for periods of GPS service outage.

"Our ToPSync platform takes the 1588v2 protocol and makes it a game changer in wireless backhaul because it enables brand new markets for wireless carriers," said Rich Lansdowne, Product Group Manager at Semtech. "The ACS9593 makes this especially true for smaller base stations that are now shaking up the industry."

Semtech's ToPSync product platform gives carriers a cost-effective way to adopt IEEE1588v2 synchronization solutions and move away from intricate GPS systems that have high installation costs and require the ability to access GPS satellites. The Semtech IEEE1588v2 system is much more ubiquitous and has no ongoing operating costs.

AT&T Tries to Block Sprint/Clearwire Merger



Wireless providers Sprint and Clearwire have recently formed a partnership to develop and eventually deploy their WiMAX networks in the USA (service is currently available in some parts of the world, including India and Pakistan), and LTE producers AT&T are making an effort to prevent the merger from going through.

AT&T appealed to the FCC to keep the Clearwire/Sprint merger from going through, essentially to buy themselves some time to introduce their LTE broadband services. Neither Sprint nor Clearwire has the capabilities to roll out WiMAX coverage in a timely manner without the other.

So long as the FCC ignores AT&T and allows Sprint/Clearwire to move forward, it is expected that the service could become available in select USA metro areas by the end of the year, including DC, Chicago, and Baltimore..

WiMAX Coverage Spreads to Asia and Australia

WiMAX service in the USA and Europe is still several months away (minimum), but the service is already being used in other parts of the world. India and Pakistan have been the "test markets" for quite some time now, but with the help of companies like Motorola WiMAX coverage is beginning to spread.

The residents of South Australia's Yorke Peninsula have until now only had access to dial-up and a limited broadband network, but ISP Internode has created a WiMAX network in the region and is even offering the service for FREE to eligible users.

Similar progress is being made in Asia, albeit not free of charge. Along with provider NEC, a small network of a Thailand hospital and two nearby clinics have been connected to WiMAX service with Motorola technology. This is a huge boon to the medical industry, as it will allow the hospitals and their associated clinics to communicate wirelessly, participate in video teleconferences, and share important test results via high-speed broadband. Such a networking solution could really change the way their medical care is delivered and the efficiency with which patients can be treated.

In China, ZTE Corp, a telecom equipment and cell phone provider, has reached a deal with Columbia's Emcali service to begin building out a WiMAX network, and REDTone (a service provider) is hard at work in eastern Malaysia creating a WiMAX network using Motorola systems.

The Malaysia contract marks Motorola's 21st contract in 17 countries, giving them a huge chunk of the market share. Expect to see a lot more of them, from installations to modems when the time comes.
