Abstract
Aspects of the disclosure provide a method and an apparatus for clock and data recovery. The method and apparatus can increase jitter tolerance, and can provide recovered data with reduced jitter amplitude. The method for recovering data transmitted over a channel can include detecting a phase of a data transition within a full unit interval that includes an active zone and an inactive zone that are set based on a jitter characteristic for the channel, generating a phase directive when the phase of the data transition is located within the active zone, and adjusting a data sampling phase based on the phase directive, so that the data transmitted over the channel is sampled at a data transition edge free location.
