Abstract
A method of controlling sampling frequency and sampling phase of a sampling device from a value generated by an equalizer coupled to the sampling device includes the steps of generating a complex representation of the value developed by the equalizer and generating a representation of a decision from an output of the equalizer. The complex representation and the decision representation are correlated to obtain a sampling error estimate. The sampling error estimate is used to adjust the sampling frequency and sampling phase of the sampling device.
