ABSTRACT:
A high speed serial link method is provided, using a data driver and a replica driver structure, the replica driver structure comprising a replica driver, a calibration engine and a peak level detector. The calibration engine compares a peak level detector output to a reference value and responsively performs a data driver adjustment, wherein the data driver adjustment comprises at least one of a driver biasing adjustment, a driver intermediate stage bandwidth adjustment and a driver equalization setting adjustment. In some embodiments, the calibration engine incorporates a comparator and a digital state machine; in other embodiments, it incorporates an analog operational amplifier.
