Abstract: A fractional-N synthesizer and method of phase synchronising the output signal with the input reference signal in a fractional-N synthesizer by generating a synchronisation pulse at integer multiples of periods of the input reference signal and gating the synchronisation pulse to re-initialize the interpolator in the fractional-N synthesizer to synchronize the phase of the output signal with the input reference signal.
