General Description

The VSC7212 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 2.18Gb/s of duplex raw data transfer. The VSC7212 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).
