General Description

The VSC7216-01 is a quad, 8-bit parallel-to-serial and serial-to-parallel transceiver chip used for high bandwidth interconnection between busses, backplanes, or other subsystems. Four Fibre Channel and Gigabit Ethernet compliant transceivers provide up to 8.32Gb/s of duplex raw data transfer. Each channel can be operated at a maximum data transfer rate of 1088Mb/s (8 bits at 136MHz) or a minimum rate of 392Mb/s (8 bits at 49MHz). For the entire chip in duplex mode, the aggregate transfer rate is between 6.3Gb/s and 8.7Gb/s. The VSC7216-01 contains four 8B/10B encoders, serializers, de-serializers, 8B/10B decoders and elastic buffers 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 four non-encoded 10-bit transceivers.
