Abstract

See full text

A system for bit character synchronization of an 8/10 bit code being deserialized is provided by a deserializer with a skip bit function input used to move a character boundary one bit at a time, and 8/10 code error detector, a zero disparity character detector and skip pulse generator. After character sychronism is lost, the skip pulse generator is permitted to generate a skip pulse if the following sequence occurs: all bits of the old character boundary have been flushed through the logic circuits, at least one non-zero disparity character has been detected, and an 8/10 code error is detected. After character synchronism is re-acquired, then the skip pulse generator is no longer permitted to generate a skip pulse.
