Abstract
L'invention concerne les bases de temps à haute sécurité. Une base de temps comporte trois générateurs synchronisés qui délivrent chacun un signal d'horloge 2h et un signal de synchronisation Sy utilisé pour la synchronisation des trames. Chaque générateur comporte un oscillateur piloté par un comparateur de phase recevant les trois signaux d'horloge et par un circuit d'asservissement interne recevant un signal de synchronisation extérieure et/ou un signal lié au signal de synchronisation Sy étant synchronisé par un circuit majoritaire recevant les signaux de synchronisation Sy des trois générateurs. Application aux installations de traitement de l'information, et notamment les centraux téléphoniques.
