摘要： An apparatus including a receiver coupled to receive an input signal from a communication link and operable to employ decision feedback equalization to the input signal of the communication link and generate an edge sample signal. The apparatus also includes a timing recovery module coupled to the receiver and operable to receive the edge sample signal and use the edge sample signal to generate a data sampling phase signal, wherein the edge sample signal influences a settling point of the data sampling phase signal.

摘要： A method comprises receiving an input signal at an input of a receiver and retrieving a data sample signal and an error sample signal from the input signal. The method also comprises applying an adaptive procedure to generate a feedback code using the data sample signal and the error sample signal for feeding back into a decision feedback equalization (DFE) module. Further, it comprises converting the feedback code into a corresponding voltage value and assigning the corresponding voltage value as a tap weight for the DFE module. Finally, it comprises generating an edge sample signal by applying DFE to the input signal using the DFE module, wherein the DFE is based on the tap weight.
