Enhanced ZDB feedback methodology utilizing binary weighted techniques

摘要

An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to present a plurality of output clock signals in response to a reference clock signal and a feedback signal. The second circuit may be configured to select one of the plurality of output clock signals as the feedback signal in response to a first control signal. The first control signal may be configured to minimize a difference in delay between the plurality of output clock signals.
