Abstract:
An apparatus and method for generating phase-related clocks are disclosed. A clock input is delayed by an alignment magnitude to generate a first phase signal. The first phase signal is delayed by the phase alignment magnitude to generate a first phase delay signal. The clock input is delayed by a phase delay magnitude to generate a second phase signal and the second phase signal is delayed by about the phase delay magnitude to generate a last phase delay signal. A phase difference is detected between the first phase delay signal and the last phase delay signal and adjustments are made to at least one of the phase delay magnitude and the alignment magnitude.
