ABSTRACT:
A parallel sync circuit comprising a serial-to parallel converter for converting an input serial into a corresponding parallel signal, a phase detector for detecting possible phase of a sync word in the parallel signal and generating a phase signal responsive thereto, a sync word generator for receiving the phase signal and in response generating a phase shifted stored version of the sync word, and a correlator for comparing the parallel signal to the phase shifted stored version of the sync word and in the event of substantial identity therebetween generating an output signal for indicating detection of the sync word.
