ABSTRACT:
Simultaneously detecting both frame and bit synchronization in a serial bit stream reduces the time required to have a receiver lock up to a transmitted serial data signal. A dual-phase correlator circuit is used to detect frame synchronization while a multiphase commutator circuit detects bit clock synchronization.
