Abstract
Systems, methods, and circuits extract data from an oversampled data stream in the presence of noise and/or jitter. Pointers decide which data samples of the oversampled data stream are extracted. Some of the pointers occurring right after a data transition are positioned based on the location of previous pointers, rather than using the data transition points as occurs during an alignment. Settings such as the frequency of how often a pointer is aligned with a data transition and a maximum adjustment amount during an alignment may be programmable.
