ABSTRACT:
A N-stage synchronizer for generating a synchronous signal that is derived from multiple sources. The synchronizer has an edge detector and N-1 stages for each asynchronous source signal. The outputs of the N-1 the synchronizer stages are processed according to an OR function. After the OR function, the merged asynchronous source signals are input to the shared last synchronizer stage. The output of the last synchronizer stage is the synchronous signal. The N-stage synchronizer reduces capacitance associated with the synchronizer and, therefore, lessens the time to assert or de-assert the synchronous signal, and reduces the time necessary to generate the synchronous signal.
