Abstract

L'invention concerne un circuit d'horloge locale pour un grand ensemble électronique. Le signal d'horloge reçu CLM est filtré 21 et 23 puis applique à une boucle de verrouillage en phase 30. Selon l'invention, des moyens 31 sont prévus pour détecter le verrouillage de la boucle et appliquer à l'entrée de remise à zéro R de la bascule 21 soit la sortie du circuit de retard 23 lorsque la boucle n'est pas verrouillée soit le signal de sortie diamétre S1 de la boucle lorsque celle-ci est verrouillée. L'invention s'applique aux centraux téléphoniques électroniques.
