Starting from an input signal (data) and a clock signal (clk), this device supplies an output signal (CKREF0) identical to the input signal but resynchronized with the clock signal. It comprises two cascaded D-type flip-flops (63, 65), the clock signal of the second flip-flop being inverted (62) with respect to that of the first flip-flop. The first flip-flop has its output coupled to the data input of the second flip-flop via a multiplexer (64), which is controlled by a signal (d-Ph) containing information about the phase relationship between the input signal and the clock signal, in such a manner that either input signal or the signal from the first flip-flop is applied to the input of the second flip-flop. This device can be used in a known phase control loop comprising an oscillator whose frequency is controllable, a frequency divider, and a phase comparator.
