Page 2: ...nstallation and operation of the EtherREGEN Technical Highlights EtherREGEN has two isolated data power clock domains Each isolated domain is re clocked using 10GHz capable ultra low jitter less than 0 8 picoseconds differential flip flops The clocking system runs from an advanced programmable jitter attenuating clock synthesizer with four differential outputs It is referenced to an ultra low jitt...

Page 3: ... clock phase noise The clock phase noise travels on the Ethernet signal itself and on power and ground planes Every signal edge coming out of any digital device carries the jitter phase noise of the clock used to clock out that edge this shows up on the ground plane and affects the threshold of chips clock inputs This is an oversimplification of a complex subject we may publish to our web site a w...
