Abstract
An integrated circuit having a receiver that selectively inhibits incoming data from being used to update adaptively generated controls. Sampling circuitry generates a plurality of samples of an incoming signal. Control circuitry generates an inhibit signal in either a first state or a second state according to whether the plurality of samples meets a randomness criterion. Tap weight update circuitry receives the inhibit signal from the control circuitry and updates a plurality of equalizer tap weights based on the plurality of samples if the inhibit signal is in the first state. The tap weight update circuitry refrains from updating the plurality of equalizer tap weights based on the plurality of samples if the inhibit signal is in the second state.
