Device for synchronizing a clock in relation to an incident digital signal, in particular at high transmission rates

摘要

The device comprises preprocessing circuitry which deliver to a phase locked loop a preprocessed signal obtained from a replica of the incident digital signal staggered in time by a fraction of the cycle of the clock signal of the phase locked loop. This device then allows a fast synchronization of the clock of the phase locked loop in relation to the incident digital signal, in particular at high transmission rates.
