The disclosed communication unit includes synchronization circuitry having a sync sequence match detector and a decode detector. Upon matching a received sync sequence or word with a known sync sequence, the sync word (or, e.g., the block containing the received sync sequence) is decoded to determine whether the block is correctable (or more generally, whether the signal quality is above a threshold). When a match is found and the sequence/block is correctable, an appropriate sync indication is outputted. Additional information, such as color code matching of consecutive sync words, may also be used before determining synchronization has been achieved.
