A method can be used for managing the operation of a phase-locked loop. The loop includes an oscillator voltage controlled by a control signal and a phase comparator receiving a reference signal and a feedback signal which arises from the output signal of the oscillator. The method includes a detection of a possible absence of transitions on the feedback signal for a first duration and, in response to such an absence, a forcing of the lowering of the voltage of the control signal at least until a reappearance of transitions on the feedback signal.
