US Patent 7447971 Data recovery systems and methods

Systems, methodologies, media, and other embodiments associated with data recovery are described. One exemplary system embodiment includes a sampling logic configured to sample data from a data line using a timing reference that is selectable from a plurality of timing reference signals. The system may also include a symbol history logic configured to track a symbol history of the data sampled by the sampling logic and a timing selection logic configured to select the timing reference used to sample the data based on the symbol history of the data to compensate for inter-symbol interference.
