The Tundra Tsi568A serial RapidIO switch is now sampling. The part delivers the performance, power, and configurability needed by embedded designers to build reliable, high-speed communications systems in wireless infrastructure, networking, and emerging architectural standards, such as Advanced Telecom Computing Architecture (AdvancedTCA). The Tsi568A interconnects serial RapidIO enabled processors and peripheral devices and supports an aggregate bandwidth of 80 Gbits/s. Based on the Serial RapidIO specification, the IC incorporates SerDes functionality, error recovery, priority-based fabric routing, high payload efficiency, and table-based fabric routing. Designers can take advantage of the switch's multiple port widths and speed configuration options to efficiently manage power requirements. It's offered in a 27- by 27-mm package with a lead-free variant. Volume pricing is under $99. Documentation, including user manuals, reference schematics and software drivers, is available at www.tundra.com.
