Method and system for link jitter compensation including a fast data recovery circuit
Abstract:
A method and apparatus, in some embodiments the apparatus includes a sampler, using a plurality of sampling clocks, to sample a first set of data of an incoming data signal to determine a first phase shift indicator and to sample a second set of data of the incoming data signal to determine a second phase shift indicator, a data recovery circuit (DRC) including control logic to determine a phase control signal based on the first and the second phase shift indicators, and a phase interpolator to receive the phase control signal and adjust a phase of the sampling clocks, wherein the phase interpolator provides the plurality of sampling clocks.
