IDT Serial RapidIO®-Based Switch Provides Significant System Advantages for ZTE’s Advanced 3G Communication Products
June 3, 2008


SAN JOSE, Calif., June 3, 2008 – IDT® (Integrated Device Technology, Inc.; NASDAQ: IDTI), a leading provider of essential mixed signal semiconductor solutions that enrich the digital media experience, today announced that ZTE, a leading global provider of telecommunications equipment and network solutions, has adopted the IDT central packet switch (CPS) solution for its WCDMA Node-B/baseband card to be used in advanced third-generation (3G) communication products. The IDT CPSsolution provides ZTE the performance and functionality, particularly the high-speed serial I/O switch, needed to ensure their customers can achieve superior flexibility, scalability and power efficiency along with improved time to market.
The CPS family of Serial RapidIO® (sRIO®)-based devices enables ZTE to provide industry-leading flexibility through combinations of performance, cost, and function, specifically  4x and 1x port options coupled with enhanced features for system bring-up and debug. The optimized performance features of the IDT CPS solution fit the design requirements for ZTE to develop next-generation 3G solutions and products.
We are very excited ZTE has chosen the IDT CPS solution because it reinforces that we are well positioned to meet this leading telecommunications provider’s requirement to produce high-performance, quality and reliable products,” said Thomas Brenner, vice president and general manager of the IDT Flow Control Management division.Our customers recognize IDT as a reliable partner on technical merit and on the support that we bundle with our solutions. The IDT CPS solutionprovides value-added benefits that give ZTE the clear competitive edge in its development of 3G communication products.”
Based on proven IDT pre-processing technology, and leveraging the sRIO, Joint Test Action Group (JTAG) and Inter-Integrated Circuit (I²C) interconnect standards; the IDT CPS-16 (80KSW0002AR) switch provides an advanced feature set developed in conjunction with IDT customers to meet their specific interconnectivity needs. This feature set is built into the IDT solution to benefit customers in the design phase, while also enabling critical diagnostics during the early stages of testing, and remaining useful in the end application. The diagnostics function provides customers with added security and faster time to market. The IDT CPS device also includes a “loopback mode,” which enables customers the added flexibility to work with the physical layer of the IDT device and to quickly identify the source of any performance bottlenecks. These enhanced functions provide “kill” and “trace/mirror” capabilities that enable an added layer of security that is often critical in embedded applications.
“We are confident in the leadership IDT has shown in Serial RapidIO® switch technology. By working closely with our design team, IDT has demonstrated profound knowledge and expertise, and provided professional and timely technical support to help our design engineers overcome various challenges with baseband signal processing design. The optimized performance features of the IDT CPS solution fit the design requirements of our next-generation 3G solutions,” said Duan Xiangyang, director of WCDMA base station design department at ZTE. “IDT is a reliable partner and understands our needs. IDT also constantly provides efficient and effective technical support throughout the entire design process. We look forward to working with IDT to deliver our best-in-class next-generation WCDMA Node-B/baseband card to our customers.”
About IDT Central Packet Switch Solutions
The central packet solutions are sRIO-based switches with functionality that is central to routing packets for distribution among digital signal processors (DSPs) field-programmable gate arrays (FPGAs), other switches or any other sRIO-based devices. They can also be used in sRIO backplane switching. They support sRIO packet switching (unicast, multicast and an optional broadcast) from any of their input ports to any of their output ports. The CPS-16 offers support for up to 16 ports of 1x or 4 ports of 4x (or combinations of 1x/4x). The CPS-12 provides 12 ports 1x or 3 ports 4x (or combinations), and the CPS-8 provides 8 ports 1x or 1 port 4x with 4 ports 1x. Each switch offers full bandwidth support for its maximum port count and port speed options: the CPS-16 is 40 Gbps, the CPS-12 is 30 Gbps, and the CPS-8 is 20 Gbps. Each port can be configured for 3.125 Gbaud, 2.5 Gbaud or 1.25 Gbaud, for long haul (backplane) or short haul (board) transmission profiles, with configurable drive strengths and pre-emphasis settings. The devices include IDT technical support available from product definition to application support.
With the goal of continuously improving the digital media experience, IDT integrates its fundamental semiconductor heritage with essential innovation, developing and delivering low-power, mixed-signal solutions that solve customer problems.  Headquartered in San Jose, Calif., IDT has design, manufacturing and sales facilities throughout the world. IDT stock is traded on the NASDAQ Global Select Stock Market® under the symbol “IDTI.” Additional information about IDT is accessible at
