Method and apparatus for transmitting and receiving both 8B/10B code and 10B/12B code in a switchable 8B/10B transmitter and receiver

摘要

A method and apparatus for using a modified 8B/10B system for transmitting 10 bit wide data packets in 12 bit code in which 5B/6B encoder/decoders separate the 10 bit wide data into two 5 bit nibbles. Unique special codes are provided which are not capable of aliasing with other 12 bit code words to provide reliable byte boundaries.
