US Patent 10972249 System and method for data sampler drift compensation

A system and method for data sampler drift compensation in a SerDes receiver. Off-data values are received at a drift compensation engine from a plurality of data value selectors coupled to one of a plurality of data sampler pairs of a speculative Decision Feedback Equalizer (DFE) of a SerDes receiver. A drift compensation value for each of the data samplers is generated by the drift compensation engine based upon the off-data values received from each of the plurality of data value selectors and, a sampling level of each of the data samplers of the plurality of data sampler pairs of the DFE is adjusted based upon the drift compensation value from the drift compensation engine.
