Product Summary
The VSC7212RG is an 8-bit parallel-to-serial and serial-to-parallel transceiver chip used for high bandwidth interconnection between busses, backplanes, or other subsystems. A Fibre Channel and Gigabit Ethernet compliant transceiver provides up to 2.18 Gb/s of duplex raw data transfer. The VSC7212RG can operate at a maximum data transfer rate of 1088Mb/s (8 bits at 136MHz) or a minimum rate of 784Mb/s (8 bits at 98MHz). The VSC7212RG contains an 8B/10B encoder, serializer, de-serializer, 8B/10B decoder and elastic buffer which provide the user with a simple interface for transferring data serially and recovering it on the receive side. The device can also be configured to operate as a non-encoded 10-bit transceiver with redundant I/O.
