A Phase-locked loop circuit including: a local oscillator, configured to generate a timing signal; a variable-length shift register, controlled by the timing signal; and a feedback control circuit, which receives a pulsed input signal and receives a local signal from the shift register. The feedback control circuit detects whether each pulse of the input signal respects a condition of temporal proximity with a corresponding pulse of the local signal and detects, for each pulse of the input signal that respects the proximity condition, whether the edge falls early, late, or within a predefined portion of the corresponding pulse of the local signal. The feedback control circuit controls the length of the shift register and the frequency of the timing signal, as a function of the detections made.
