The Tundra Tsi577™ is a fifth-generation RapidIO switch. The Tsi577 supports 40 Gbps aggregate non-blocking bandwidth at lower power than previous RapidIO switches.

Using the Tsi577, flexible port configurations can be selected through multiple port width and speed options. The Tsi577 can be configured as a 16-port x1 mode switch or a 4-port x4 mode switch (or various combinations of x1 and x4 modes). Each port on the device can be a single x4 mode port or four x1 mode ports and can operate at 1.25 Gbaud, 2.5 Gbaud, or 3.125 Gbaud (or any speed in between on a quad grouping basis).

The Tsi577 contains all the benefits of the previous RapidIO switch generations, including:

• Industry best multicast performance
• Traffic management through scheduling algorithms
• Programmable buffer depth
• Fabric performance monitoring to supervise and manage traffic flow
• Reduced number of clocks
• Smaller package size for 16x1 solutions
• Low short and long reach power
• Industry best signal integrity
• 110 ns cut-through latency

Business Benefits

• Scalability - Single solution for mesh, fabric, and aggregated systems
• Performance - Improved system and distributed processing performance
• Power - SerDes implementation for low-power solution
• Ease of design - Simplified board layout with one clock source
