Abstract

A circuit includes a frequency detector generating a comparison signal as a function of a comparison between a reference signal and a feedback signal. An oscillator generates an output signal as a function of the comparison signal. A frequency divider, in operation, divides the output signal by a division value to produce the feedback signal as having a frequency that is a multiple of a frequency of the reference signal. A frequency counter circuit measures the frequency of the reference signal and generates a count signal based thereupon. A control circuit adjusts the division value used by the frequency divider, in operation, based upon the count signal.
