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.

Abstract: In one embodiment, a processing system includes an interface controller to receive a data signal from a remote link partner over a link, and recover a clock signal from the received data signal, frequency generation circuitry to receive the recovered clock signal, and output a local clock signal responsively to the received recovered clock signal, wherein the interface controller is configured to drive a transmit symbol rate responsively to the local clock signal, and a digital control loop including the interface controller and the frequency generation circuitry, wherein the interface controller is configured to identify a clock drift, generate a digital control signal responsively to the clock drift, and send the digital control signal to the frequency generation circuitry, which is configured to adjust a frequency of the local clock signal responsively to the digital control signal in order to reduce the clock drift.
