Abstract
A circuit and method of adjusting a sample point for a data stream to account for intersymbol interference is disclosed herein. The system averages the amount of intersymbol interference occurring for a specific data pattern and uses this average value which reflects a phase difference between the leading edges of two pulses to determine at which clock count a sync pulse should issue to sample and read a data value.
