The IDT 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).
