VSC7226

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 channel's 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 channel's 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. Each transmitter may be supplied 8-bit data which will be encoded into 10-bit characters for transmission, or may be supplied pre-encoded 10-bit data in which case the internal encoder is bypassed. The four channels may operate independently or in a synchronized mode transferring data that is word-aligned across 16 or 32 data inputs.
