Abstract
A reception device is able to receive packets in a communication network comprising at least two stations. The device is capable of receiving packets containing samples of the network which originate from data sampled every period T, where Temanates from a time base synchronized on all the stations of the said network; regenerating a counting ramp with the aid of a loop receiving the samples and furthermore delivering local samples every period Tand a clock. The phase-locked loop comprises: a samples comparator comparing the samples and the local samples and delivering an error signal; a corrector receiving the signal and delivering a corrected error signal, the corrector having a static gain equal to 1; a digital oscillator receiving the corrected error signal and delivering the clock, which has a frequency dependent on the signal and is proportional to a gain. According to the invention, the phase-locked loop comprises, furthermore, a gain adjustment device which determines a gain value as a function of the error signal.
