ABSTRACT:
A sync finder includes a pulse jitter detect module to select N-bit segments of an M-bit sync pattern at predetermined positions and to compare the N-bit segments to expected N-bit segments. A pulse verifying module generates a first signal in response to the expected N-bit segments matching the N-bit segments. N and M are integers greater than 1 and M>N.
