Abstract
A circuit for detecting a serial signal comprises a first circuit coupled to receive the serial signal during a predetermined plurality of time periods of substantially equal duration. The first circuit is coupled to receive a first code. The first circuit is arranged to compare a part of the serial signal corresponding to each time period of the plurality of timer periods to the first code, thereby producing a match signal. The first circuit accumulates the match signal from each of the each time period of the plurality of time periods.
