Abstract
Data recovery, as well as associated circuitry and system, is described. An input word stream having a word width of at least one word is obtained and a sliding window is applied to it to resolve phases. Scores for phases are determined at least in part by: subdividing the sliding window into sample portions; applying a homogeneity function to each of the sample portions to determine respective values therefor; and summing sets of the values respectively associated with the phases to provide the scores. A score is selected from the scores according to at least one criterion to select a phase from the phases. A portion of a delayed version of the input word stream is sampled by application of the sliding window thereto using the phase selected to output sampled bits.
