Receiver circuitry is disclosed that can take circuit branches offline to possibly adapt an offset value. In one embodiment, a circuit in a receiver has at least two branches. Each branch includes an adjustor to adjust the branch signal by an offset value. Selection circuitry takes one of the branches offline by selecting the output of that branch as an offline value, and by selecting the output of one or more of the other branches as a data decision value. The selection circuitry changes which branch is taken offline during the operation of the circuit. When a branch is taken offline, an offset value associated with that branch may be updated, if necessary.
