Serial RapidIO switch targets DSP-intensive processing apps

Ottawa, Canada—Tundra Semiconductor Corp. expanded its Serial RapidIO switch family with a device that is designed to perform DSP aggregation on line cards in wireless, networking and video infrastructure applications.

The Tsi574 switch interconnects Serial RapidIO-enabled microprocessors, DSPs, FPGAs, and peripheral devices, supporting an aggregate bandwidth of 40-Gbits/s. The Tsi574 is configurable, enabling designers to efficiently manage power requirements. Its port flexibility supports up to four 4x mode ports or up to eight 1x mode ports, with each port configurable to 1.25 Gbits/s, 2.5 Gbits/s or 3.125 Gbits/s. All of the switch's ports are independent and will support mixed configurations of width and speed.

The switch is based on the most recent release of the Serial RapidIO Specification v1.3. For more on the specification, click here:

The switch is capable of routing packets to more than 64,000 endpoints. It features independent unicast and multicast routing mechanisms, and error management extensions that provide proactive issue notification to the fabric controller.

The device requires 1.2-V and 3.3-V power supplies and is rated for industrial and commercial temperature operations. The switch also supports IEEE 1149.6 JTAG standard for high speed interconnects. For more on the standard, click here:

The Tsi574 Serial RapidIO Switch will be sampling in September 2006. Volume pricing for the Tsi574 is less than $80. The Tsi574 is implemented in 0.13 micron CMOS technology, and housed in a 21-mm x 21-mm, 399-ball FCBGA package.
