ABSTRACT:
A device is provided for synchronizing, on a reference clock signal, an exchange of data with a remote member. The device includes a main variable delay line controlled by a first processing unit coupled to a phase comparator in order to generate a delayed clock signal transmitted to the remote member. One input of the main variable delay line receives the reference clock signal. The device also includes a first terminal for receiving a clock signal image received by the remote member, a first auxiliary variable delay line having one input connected to the first terminal and one output connected to a first input of the phase comparator, a second auxiliary variable delay line having one input connected to the input of the main variable delay line and one output connected to a second input of the phase comparator, and a second processing unit controlling the first and second auxiliary variable delay lines so that the signal image received by the remote member is offset with respect to the reference clock signal, by a phase suitable for synchronizing the exchange of data on the reference clock signal.
