发明名称 Device for generating a sampled ramp signal representative of a synchronization signal, and device for assisting the reconstruction of a synchronization signal, for a packet switching network
摘要 A device is dedicated to assisting the reconstruction of synchronization signals, for example within an item of communication equipment of an IP network. This device comprises i) a phase-locked loop charged with reconstructing, on the basis of a second sampled ramp signal received, a reference clock signal and a second ramp signal identical to, and in phase with, that having been sampled, and ii) processing means charged with determining in a first sampled ramp signal received, representative of a synchronization signal to be reconstructed and each sample of which is associated with a sample of the second ramp signal corresponding to a determinable sampling period, the value which corresponds to the first sample of this first sampled ramp signal received as well as the sampling period corresponding to this value, and then to initialize with this value a synchronization counter which is synchronized with respect to the second reconstructed ramp signal, on the basis of the reconstructed reference clock signal.
