In accordance with the invention, an apparatus for can celing jitter from an input signal to produce an output signal with a Substantially constant period includes a pipe delay selector and a state machine. The pipe delay selector is arranged to produce the output signal. The period of the output signal is determined by the period of the input signal. The state machine is arranged to produce the select signal. The select signal enables the pipe delay selector to adjust a pipe delay according to a predetermined number of cycles of the clock signal Such that the output signal maintains a Substantially constant period. In accordance with another aspect of the present inven tion, the apparatus includes a synchronizer circuit that is arranged to produce a synchronized signal. The synchro nized signal corresponds to the input signal, and has a known timing relationship with the clock signal. In accordance with yet another …
