The present invention relates to the domain of video equipment. It relates to a phase-locked loop able to recover the timing of a synchronization signal comprising a temporal discontinuity of a maximum amplitude equal to PCR_Modulus, the loop comprising: a sample comparator comparing the samples and the local samples of a synthesised signal, means for producing the synthesised signal from a corrected signal, a corrector receiving a comparison result delivered by the comparison means and delivering the corrected signal, According to the invention, the comparison means comprises the means to determine a difference in value between the local samples and the samples of the synchronisation signal and in that the comparison result has a value that depends on the value &egr; and on the difference between the value &egr; and the value PCR_Modulus/2.
