Device for generating counter signals representative of clock signals and device for reconstructing clock signals, for a packet-switched network

摘要

A device (D 2 ) is dedicated to the reconstruction of clock signals, for example within communication equipment (EQ 2 ) of an IP network. This device (D 2 ) comprises i) a phase-locked loop (BV) having a cut-off frequency dependent, on the one hand, on a configuration value making it possible to reconstruct clock signals according to a chosen clock frequency, and on the other hand, a chosen sampling frequency, and ii) control means (MC 2 ) responsible for forcing the phase-locked loop (BV) to present a variable cut-off frequency according to a received operating mode indication.
