The present invention concerns an arrangement and process for mutually synchronizing application-specific integrated circuits (ASIC) which are arranged to communicate with one another. The arrangement according to the invention enables an activating pulse edge to be determined in a common clock signal to an edge-triggered integrated circuit which communicates with at least one further integrated circuit. Each of the communicating integrated circuits receives the common clock signal. The circuits also receive frequency data in the form of a clock signal which is adapted to the respective circuit and which is used for determining in the respective circuit the activating pulse edger in the common clock signal.
La présente invention concerne un agencement et un procédé de synchronisation mutuelle de circuits intégrés spécifiques à une application (ASIC), conçus pour communiquer entre eux. L'agencement selon l'invention permet de déterminer un flanc d'impulsion d'activation dans un signal de synchronisation commun destiné à un circuit intégré à déclenchement par flanc d'impulsion, qui communique avec au moins un autre circuit intégré. Chacun des circuits intégrés communiquants reçoit le signal de synchronisation commun. Les circuits reçoivent également des données de fréquence sous forme d'un signal de synchronisation adapté aux circuits respectifs et servant à déterminer, dans chacun des circuits, le flanc d'impulsion d'activation dans le signal commun de synchronisation.
