The IDT Tsi620 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 the IDT RapidIO Tsi switch family and adds interfaces to PCI-enabled processors, as well as an interface to low-cost FPGAs using a XGMII interface for the physical layer that transmits RapidIO at the logical layer at up to 10 Gbps.
