ABSTRACT:
Apparatus and method for detecting a sync signal in parallel data which has been reconstituted from serial data. The first occurrence of digital bits which corresponds to a predefined sync signal is recognized and causes the circuitry to shift to a mode of operation in which subsequent sync signals will be recognized if and only if they occur within a predetermined "window" around the expected position of the sync signal. The sync signal is used re-align the parallel data so that the bits are grouped into meaningful words.
