摘要：A method and apparatus for synchronising a serial data signal to a referenceclock signal, the data signal comprising frames of equal length each comprising a knownframe alignment word (FAW) and a payload, the frame alignment word being in a

consistent position within each frame, the method comprising: storing the signal in a FIFO

wander buffer as it is received in order to compensate for any wander that may occur;outputting the data signal stored in the FIFO wander buffer synchronised to the

reference clock signal; searching for at least a portion of the frame alignment word in thedata signal as it is received; and when it is determined that the frame alignment word hasbeen found, realigning the data signal within the wander buffer The step of realigning thedata may comprise replacing at least a portion of the data signal in the wander bufferwith a locally-held copy of at least a portion of the frame alignment word. The methodmay be used in any synchronous serial data stream, such as SDH or SONET.
