Ottawa, OntarioIn a move to push widespread adoption of Serial RapidIO, Tundra Semiconductor Corp. has added to its product portfolio a switch that is designed to connect RapidIO technology from the local interconnect to the backplane in DSP-based applications.
The Tsi576 12-port Serial RapidIO switch is based on the most recent release of the Serial RapidIO specification v1.3. For more on the standard, click here: www.rapidio.org/specs/current. Serial RapidIO is an open-standard, switched fabric technology aimed at replacing proprietary backplane protocols. It is supported by several major chip makers, including Freescale Semiconductor, IDT, Mercury Computing Systems, Texas Instruments and Xilinx.
Suitable for local DSP and processor aggregation backplanes, the Tsi576 Serial RapidIO switch targets applications such as wireless baseband line cards, media gateways and video head end equipment where data from large clusters of DSPs are aggregated and routed on larger bandwidth ports to switch cards in the backplane.

The Tsi576 switch interconnects Serial RapidIO-enabled microprocessors, DSPs, FPGAs, and peripheral devices, supporting an aggregate bandwidth of 40 Gbits/s. It offers designers configuration options to efficiently manage power requirements.
The Tsi576's port flexibility supports up to two 4x mode ports and eight 1x mode ports, or up to twelve 1x mode ports. Each port is configurable to 1.25 Gbits/s, 2.5 Gbits/s or 3.125 Gbits/s. All of the switch's ports are completely independent.
Using an enhanced SerDes, the Tsi576 delivers incremental port power of 200-mW. It also features hardware multicast for improved distributed processing performance.
The Tsi576 Serial RapidIO Switch will be sampling in October 2006. Volume pricing for the Tsi576 is under $90. The Tsi576 is housed in a 21-mm x 21-mm, 300-ball FCBGA package.
