Abstract
In one embodiment, a communication system includes network devices, each comprising a network interface to receive at least one data stream, a given network device being configured to recover a remote clock from the at least one data stream received by the given network device, a frequency synthesizer to generate a clock signal and output the clock signal to each of the network devices, wherein the given network device is configured to find a clock frequency differential between the clock signal and the recovered remote clock, and provide a control signal to the frequency synthesizer responsively to the clock frequency differential, the control signal causes the frequency synthesizer to adjust the clock signal so as to iteratively reduce an absolute value of the clock frequency differential between the clock signal and the recovered remote clock.
