  • Integrated data clock extractor
    Patent number: 6795514
    Abstract: A circuit for extracting a data clock signal from an input data stream, comprising a programmable delay element for receiving an arbitrary clock signal, delaying the arbitrary clock signal by a variable programmable amount and in response generating an extracted data clock signal, and a clock phase detector for comparing logic level transitions of the input data stream with transitions of the extracted data clock signal and in response generating a delay adjust signal for defining the variable programmable amount of delay such that the transitions of the input data stream are substantially aligned with the transitions of the arbitrary clock signal.
