The IDT Tsi576 is a third-generation RapidIO® switch. Supporting 40 Gbps aggregate bandwidth, the Tsi576 enables customers to develop high performance systems at low cost. The device is targeted at chip-to-chip DSP and processor aggregation and connection to network/backplane uplinks. The Tsi576 can be configured as a 12-port x1 switch or a two-port x4 plus eight x1-port switch (or various combinations of x1 and x4). In the "eight plus two" configuration, the two-port x4 are used to aggregate traffic from local DSP or processor clusters serviced by the up to eight x1-ports. Each of the ports can be run at 1.25 Gbaud, 2.5 Gbaud, or 3.125 Gbaud.
