ABSTRACT:
A data transmission error reduction circuit is formed including a delay circuit, a detection circuit and a control circuit. In one embodiment, the delay circuit includes n delay element and multiplexor pairs, selectively employable to apply an aggregate amount of time delay to a data signal. The detection circuit includes circuit elements to detect a critical reference time distance between a reference point of a data signal and at least a selected edge of a clock signal being smaller than a desired threshold. The control circuit includes circuit elements to dynamically control the aggregate amount of time delay applied by the delay circuit based at least in part on the detection of the detection circuit. In one application, m units of the data transmission error reduction circuit are correspondingly employed to reduce data transmission errors on m high speed parallel data signals of a data interface.
