Abstract

Procédé de gestion du fonctionnement d'une boucle à verrouillage de phase (BV), la boucle comprenant un oscillateur contrôlé en tension (16) par un signal de contrôle (SC) et un comparateur de phase (14) recevant un signal de référence (CKIN) et un signal de retour (CKFB) issu du signal de sortie (SS) de l'oscillateur (16), le procédé comprenant une détection d'une absence éventuelle de transitions sur le signal de retour (CKFB) pendant une première durée et en réponse à une telle absence, un forçage de la décroissance (DWN) de la tension dudit signal de contrôle (SC) au moins jusqu'à une réapparition de transitions sur ledit signal de retour (CKFB).
