Abstract
Embodiments of the invention relate to methods and circuits for controlling the sampling phase of a signal that is to be regenerated by sampling, particularly a serial communication signal, having method steps or means for oversampling the signal in order to ascertain samples of the signal during predetermined sampling phases, for determining differential errors between the samples during different instances of the predetermined sampling phases, for determining a differential error rate between the samples to at least one first and at least one second sampling phase on the basis of the ascertained differential errors, and for comparing at least two differential error rates based on at least two different sampling phase pairs in order to ascertain a decision concerning which of the predetermined sampling phases can be selected as a reference sampling phase for correctly regenerating the signal.
