Abstract

In one embodiment, a system includes a digitally controlled oscillator (DCO) to generate a local clock having a local clock frequency, and clock synchronization circuitry to receive from a device a signal indicative of a remote clock frequency, compare measures of the remote clock frequency and the local clock frequency; generate a digital control command based on the comparison; and provide the digital control command to the DCO, wherein the DCO is to adjust the local clock frequency responsively to the digital control command.
