Abstract
A system and method is presented for reducing skew between the positive and negative components of a differential signal in a high speed communications link. The communications link includes a signal generator producing and transmitting complementary positive and negative signals over separate transmission lines and a receiver receiving the complementary signals. The communication link further includes a skew compensation circuit having a skew detector, a controller, and separate delay and buffer elements for both the positive and negative component of the differential signal. The controller separately controls each of the delay or buffer elements in response to the detected skew between differential signal components.
