The Tsi564A™ is part of Tundra’s family of second-generation RapidIO switches. Supporting 40 Gbps aggregate bandwidth, the Tsi564 enables customers to develop high-performance systems at low cost. The Tsi564 is targeted at chip-to-chip DSP and processor aggregation and comes in a small 21 mm x 21 mm package size.

The Tsi564 can be configured as a 8-port x1 switch or an 4-portx4 switch (or various combinations of x1 and x4). Each of the ports can be run at 1.25 Gbaud, 2.5 Gbaud, or 3.125 Gbaud.

With a smaller footprint than the Tsi568A™, the Tsi564A offers low power, multiple port-widths and speed configurations, making it ideally suited for applications where power, cost and board space are primary concerns.

Based on the Serial RapidIO Specification, the Tsi564A incorporates SerDes functionality, error recovery, priority-based fabric routing, high payload efficiency, and table-based fabric packet routing. In addition, the Tsi564A supports RapidFabric extensions including data streaming packet switching for interworking and encapsulation.

The device goes beyond standard specification requirements to solve system level issues with low power consumption, and hot swappable I/Os. The extensive buffering and traffic management architecture is specifically designed for line rate termination and the prevention of head-of-line blocking.

Business Benefits

Improves Overall System Performance

• Easy implementation of distributed processing between DSPs in clusters
• Frees up DSPs resources for actual application processing versus terminating protocol stacks in software.
• Superior real-time image processing resolution, size and frames per second in military and medical imaging systems
• Configurability provides more product variants per development dollar

Power

• Tunable power per port to optimize budget for application. With competing synchronous switches all ports must operate at the frequency of the highest speed port resulting in higher power dissipation.
• Provides more processing power-per-watt through distributed processing
