A new adaptation strategy for the equalization of high speed binary links is presented; it reduces pattern-dependent jitter. Instead of using the LMS or a related algorithm that optimizes the vertical eye opening at the receiver, the equalizer can be optimized to reduce intersymbol. interference at data transitions, thereby targeting zero jitter. The LMS algorithm is modified to combine the two criteria and provide a trade off between vertical eye opening and horizontal eye opening at the equalizer output. Behavioral simulations verify the technique on a lossy transmission line model.
