IDT Tsi620 Evaluation Board

The IDT Tsi620 Evaluation Board (EVB) is an AMC width card that enables system OEMs to develop applications that use the Tsi620 Multi-protocol RapidIO Switch. The EVB can be used in a MicroTCA chassis or standalone.

The core of the EVB is the IDT Tsi620. This device provides the functionality of both a RapidIO switch and a non-transparent RapidIO-to-PCI bridge. The RapidIO Switch offers 50 Gbps aggregate bandwidth, while the RapidIO-to-PCI bridge enables legacy systems to link to the high-bandwidth RapidIO interconnect.

The Tsi620 contains all the benefits of IDT’s family of RapidIO switches. In addition, the device interfaces to low-cost FPGAs through an FPGA port that transmits the RapidIO logical and transport layer over an XGMII physical interface for connection to non-SerDes FPGAs.

The Tsi620 EVB allows customers to leverage the FPGA interface to an Altera Stratix III, RapidIO interface to a Texas Instruments TCI6487 multi-core DSP, and PCI-enabled processors through a PMC connector. Using the Tsi620’s hardware-based RapidIO-to-PCI bridging, customers can connect to low-cost processors and re-use existing software.

The Tsi620 EVB also offers an AMC form factor interface to add other RapidIO-enabled cards in standalone mode. Alternatively, customers can use the AMC backplane connector to network to other AMC cards in a MicroTCA chassis using RapidIO.
