ABSTRACT:
A method and an apparatus provide extraction of data from an analog signal. The method includes deriving a data-location signal having amplitude transitions that identify a phase of amplitude transitions of the analog signal, and, in response to the data-location signal, selecting a sampling clock signal having a phase different from the phase of the amplitude transitions of the analog signal. The apparatus includes a signal generator that derives from the analog signal a data-location signal, and a selector that selects a sampling clock signal having a phase different from the phase of the amplitude transitions of the analog signal.
