Abstract
The present invention relates to the domain of synchronization of items of equipment connected by a packet switching network. It relates more specifically to a system for generation of a synchronization signal (PIPA, PIPB) and a clock signal (CLK_outA, CLK_outB) by a slave station (SA, SB) connected to a master station (SM) via a packet switching network. The master station (SM) is conformed to produce a master clock signal (CLKM) of frequency Fand a master synchronization signal (PIPM). The master synchronization signal (PIPM) is in phase with the master clock signal (SM). The slave station (SA, SB) comprises the primary synthesis means (SMA, SMB) producing a slave periodic signal TICKSA, TICKSB), the periodic signal (TICKSA, TICKSB) is in phase with the master clock signal (CLKM). According to the invention, the slave station (SA, SB) also comprises the secondary means of synthesis (SMA, SMB) to synthesize a clock signal (CLK_outA, CLK_outB) and the synchronization signal (PIPA, PIPB) and in that said clock signal (CLK_outA, CLK_outB) and said synchronization signal (PIPA, PIPB) are in phase with said signal (TICKSA, TICKSB).
