Tundra Semiconductor Corp. has announced the Tsi576, a new 12-port Serial RapidIO switch that promises optimal port-width configurations to manage local and backplane interconnect for DSP-based applications using Serial RapidIO switch. With 40Gbps of non-blocking bandwidth based on Serial RapidIO Specification v1.3, the device is expected to set industry benchmarks for high performance and low power consumption.

"The price and performance per port on our new Tsi576 switch is optimized for DSP clusters with serial RapidIO ports. This switch is the optimal choice to aggregate board-level traffic to the backplane," said Tundra CTO Rick O'Connor.

Supporting IEEE 1149.6 JTAG standard for high-speed interconnects, the new device can be configured into multiple-port width and speed options to suit power requirements. The device can be configured into 12 ports with 1x-wide links to support data ranges of 1-2.5Gbps. For applications with many DSPs, or in which processors must be aggregated or connected to a backplane, the device may be configured with eight 1x-wide links and two 4x-wide links. In this design, the 4x-wide links can operate on ranges of 4-10Gbps.

Tsi576 comes in a FCBGA 21mm package and allows embedded applications to route packets to over 64,000 RapidIO endpoints through per-port hierarchical lookup tables, independent unicast and multicast routing mechanisms, and error-management extensions that provide proactive issue notification to the fabric controller. Each port in Tsi576 runs at 1.25-, 2.5- or 3.125Gbps. The device requires 1.2V and 3.3V power supplies, thus consuming less power than its predecessor, the Tsi574A.

The Tsi756 will be sampling in October 2006 with volume pricing under $90. The device is rated for industrial and commercial operations.
