ABSTRACT:
An apparatus for generating a pulse clock signal for a multiple-stage synchronizer provides a pulse clock signal to a synchronizer. The synchronizer synchronizes data received in a first clock domain, which is referenced to a first clock signal, to a second clock domain, which is referenced to a second clock signal. The apparatus includes a synchronization pulse generator and a multiplexer. The synchronization pulse generator generates a synchronization pulse based on the first clock signal and the second clock signal. The multiplexer outputs one of either the first clock signal or the synchronization pulse as the pulse clock signal based on an input control signal.
