ABSTRACT:
A test circuit receives a reference signal having a reference frequency and generates a synchronizer input signal having a synchronizer input frequency for inputting into a synchronizer circuit. A frequency generator is configured to offset the synchronizer input frequency at selectable frequencies from a nominal frequency value. An offset measurement circuit is configured to compare the frequency offset for the synchronizer input frequency with the frequency offset of a synchronizer output signal.
