Abstract
This invention provides a digital auto-phase-controlled retiming circuit which automatically locates the retiming clock phase in the center of input data eye pattern by detesting the phase difference between retiming clock and data and tracking adoptively the mutual phase variation in a case that the mutual phase difference between data and retiming clock is uncertain and changes according to time in digital transmission and/or digital signal processing systems.
