Tundra Semiconductor Corp. targets cost-sensitive applications with the introduction of the Tsi572 Serial RapidIO switch. This scalable, low-power switch is well suited for a broad spectrum of wireless, wireline and imaging/video applications.

The small form factor 21x21 RapidIO switch with 2x4 plus 4x1 or 8x1 RapidIO is designed for processor aggregation and backplane connectivity with 30Gbit/s of non-blocking full duplex bandwidth. It offers a low 120mW to 200mW per port power and low 100ns cut-through latency. The Tsi572 is interoperable and software compatible with the Tsi57x product family.

Tundra said the Tsi572 switch is the lowest-power RapidIO switch available in the market, and compliant with the RapidIO 1.3 specification. "The switch offers designers the performance and reliability of RapidIO with lower-port count and lower-power consumption at a cost for high-volume applications," it added.

"Tundra's Tsi572 RapidIO switch coupled with Texas Instrument's (TI) high performance single-core TMS320TCI6482, TMS320TCI6484 DSP or multicore TMS320TCI6487/88 DSP enables wireless base station OEMs to develop flexible, high-performance and board-area efficient channel card designs," said Kathy Brown, DSP wireless infrastructure business manager, TI.

The Tsi572 complies with the AMC.4 specification and provides a solution for RapidIO connection on AMCs and the backplane.
