Tsi578 Serial RapidIO switch

Tundra Semiconductor Corp. announced the Tundra Tsi578 Serial RapidIO switch for applications such as wireless base stations and video infrastructure.

According to the company, Tsi578 is suited for ATCA and MicroTCA backplane or processing connectivity. These platforms are said to benefit from the switch's ability to route packets to over 64,000 endpoints, independent unicast and multicast routing mechanisms and error management extensions that provide issue notification to the fabric controller.

This switch interconnects Serial RapidIO-enabled processors and peripheral devices, supporting an aggregate bandwidth of 80Gbps. The Tsi578's port flexibility supports up to eight 4x mode ports or 16 1x mode ports, with each port configurable to 1.25Gbps, 2.5Gbps or 3.125Gbps. All of the switch's ports are completely independent and will support mixed configurations of width and speed.

The Tsi578 integrates several features that are said to leverage the capabilities of the Serial RapidIO interconnect protocol. The switch has low latency between ports and each port has optional store and forward or cut-through modes. In addition, there is traffic management through three fabric scheduling algorithms and programmable buffer depth. Fabric performance monitoring enables supervised and managed traffic flows.

The Tsi578 Serial RapidIO Switch will be sampling in August 2006. Volume pricing for the Tsi578 is under $99. The Tsi578 is implemented in 0.13?m CMOS technology, is forward compatible with the Tsi568A and is packaged in a 27-by-27mm, 675-ball FCBGA package. The device requires 1.2V and 3.3V power supplies and is rated for industrial and commercial temperature operations. The switch also supports IEEE 1149.6 JTAG standard for high speed interconnects.
