Abstract

An apparatus and method for generating phase related clocks, includes delaying a clock input by a cycle delay magnitude to generate a cycle delay signal and N delay taps is disclosed. Each delay tap has a delay equal to a fractional amount of the cycle delay magnitude. The method further includes delaying the clock input by an alignment magnitude to generate a first aligned phase signal and delaying each of the N delay taps by fractional amounts of the alignment magnitude to generate N phase aligned signals. A feedback loop is closed by a phase comparison between the first aligned phase signal and the cycle delay signal. The phase comparison result is used to adjust the cycle delay magnitude, which adjusts delays of the cycle delay signal and the N delay taps, and adjust the alignment magnitude, which adjust delays of the first aligned phase signal and the N phase aligned signals.
