摘要
The present invention provides a simple, easy to implement method and apparatus to reduce jitter in a channel and expand the eye width and eye height of the eye pattern of the signal. The method and apparatus of the present invention reduces jitter specific to a channel in a high speed interface. The present invention utilizes a phasing shifting mechanism based on history of the incoming bits at the receiver. The input bits from the channel are shifted in time before getting to the receiver. This approach significantly reduces Intersymbol Interference (ISI) and deterministic jitter, thus opening up the eye width and eye height for a given interface.
