Abstract

Apparatus and method for reducing clock skew. A compensator is connected to receive an uncorrected clock signal and delay the clock signal in accordance with a skew control voltage. The skew control voltage is derived from the signal to noise ratio of an analog signal produced by a device controlled by the clock signal. The skew control voltage changes step wise maintaining the system signal to noise at a minimum by reducing the clock skew.
