Abstract:
A skew adjustor that can reduce inter-pair skew between differential signals received via a cable is disclosed. In one embodiment, a skew adjustor includes: a skew detector that receives signals from a cable, and provides a detected skew amount when skew is detected between two of the signals; an offset controller for receiving the detected skew amount, and for providing a delay control signal in response thereto; and a skew delay circuit that receives the signals and the delay control signal, and enables one or more delay stages in a path of a first arriving of the two skewed signals based on the delay control signal, such that an adjusted skew between the two skewed signals at an output of the skew delay circuit is less than the detected skew amount by an amount corresponding to the enabled one or more delay stages.
