GENERAL DESCRIPTION :
The VSC7226-01 and VSC7226-02 are quad channel parallel-to-serial and serial-toparallel transceiver chips designed for use in high bandwidth data transmission between busses, backplanes and other subsystems. Each channels transmitter section contains parallel 8-bit or 10-bit SSTL_2 input circuitry, an 8B/10B encoder, serializer and a pair of serial PECL output drivers and additional control inputs. Each channels receiver section contains a pair of PECL inputs, clock and data recovery circuitry, a deserializer, an 8B/10B decoder, elastic buffers, 8- bit or 10-bit SSTL_2 output drivers and additional control outputs.
