Abstract
A circuit for preserving a predetermined timing relationship between a synchronization signal including periodic sync codes and a digital signal composed of successive frames of which the nominal duration is equal to the period of the sync codes includes a delay device connected to receive the digital signal. The delay device is selectively adjustable to impose a controllable delay on propagation of the digital signal. A FAW detector detects a frame alignment word in the digital signal, and a time measurement circuit measures the time that elapses between occurrence of a sync code and detection of a frame alignment word. A delay adjustment circuit is responsive to the time measurement circuit to adjust the delay imposed by the delay device.
