Abstract
An apparatus for and method of generating a signal for equalizing propagation delay among parts of a transceiver are disclosed. The parts each have a plurality of channels, and each channel is configured to receive the signal. The apparatus includes a master circuit and a dummy channel circuit. The master circuit is configured to receive and lock to a reference clock signal, and in accordance therewith generate a reference delay signal and an adjusted clock signal. The dummy channel circuit is configured to receive the adjusted clock signal, the reference delay signal and a dummy data signal, and in accordance therewith generate an intermediate data signal, the dummy data signal and one or more control signals. The control signals correspond to a delay between the adjusted clock signal and the intermediate data signal. In this manner a uniform delay may be provided to all parts and channels.
