The Tsi568A™ is Tundra’s second-generation RapidIO switch. Supporting 80 Gbps aggregate bandwidth, the Tsi568 enables customers to develop high-performance systems at low cost.

The Tsi568 can be configured as a 16-port x1 switch or an 8-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.

The Tsi568 is targeted at the following:

• Chip-to-chip DSP and processor aggregation
• Board-to-board backplane interconnect
• Chassis-to-chassis interconnect over copper or optics

The Tsi568A supports open architectural standards such as AdvancedTCA and VITA VXS.

Based on the Serial RapidIO Specification, the Tsi568A incorporates SerDes functionality, error recovery, priority-based fabric routing, high payload efficiency, and table-based fabric packet routing. In addition, the Tsi568A supports RapidFabric extensions including data streaming packet switching for interworking and encapsulation.

The device goes beyond standard specification requirements to solve system level issues by optimizing performance, lowering power consumption, and supporting 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.
• Free up DSPs resources for actual application processing vs. terminating protocol stacks in software.
• Superior real time image processing resolution, size and frames per second in military and medical imaging systems

Reduced Power Dissipation

• 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.
