System that compensates for variances due to process and temperature changes

A device and method that adjust data due to temperature variations is disclosed. The data is captured in a multi-stage delay line. A first controller parses the data and identifies an Edge1 value and an Edge2 value for bits in the delay line. The edge values are used to generate signals that set a Multiplexer 1 (MUX1) and a Multiplexer 2 (MUX2) to select bits from the delay line. A second controller processes an edge sample from bits in the delay line to determine if the data has shifted in the delay line relative to the current multiplexer settings. An edge sample is a snapshot of the delay line values. The new edge values generated by the second controller are selectively filtered and integrated with initial edge values to generate new settings for the MUX1 and MUX2.
