<p>A network device for determining an optimal sampling phase for source synchronous data received on a data communications channel. The network device includes a transmitter clock domain for providing a data pattern along with a synchronous free-running clock. The network device also includes a plurality of phases of a core clock. The network devices further includes means, in a core clock domain, for sampling a data pattern generated by the received clock with the plurality of phases to determine the optimal phase for sampling the data received from the external device.
