ABSTRACT:
A circuit and method to synchronize with a data transmission having a plurality of data transmission frames each with a start boundary identified by a predetermined synchronization pattern, includes comparing sets of data within the data transmission to a predetermined synchronization pattern. A frame tracking signal is assigned to each one of the plurality of comparison results that indicates a match between a data pattern within one of the plurality of sets of data and the predetermined synchronization pattern, including matches that occur multiple times within a known duration of the data transmission frame duration. Based on each frame tracking signal assigned to a comparison result, the start boundary of the data transmission frames is searched. The start boundary may be search by monitoring successive occurrences of the predetermined synchronization pattern in the data transmission at intervals of the known data transmission frame duration for each data matching data pattern. If the predetermined synchronization pattern occurs successively in the data transmission, the associated data pattern is confirmed as the synchronization pattern in the data transmission, and synchronization with the data transmission is achieved.
