Abstract:
An integrated circuit includes a decision feedback equalizer (DFE) including a first and second digital equalizer logic including circuitry to compensate first and second bits in a received stream and to provide first and second sign bits. The second equalizer logic can run concurrently and can be connected in parallel relative to the first equalizer logic. The second equalizer logic can include a low and high sign bit pipelines providing first and second conditional sign bits by assuming a low and high sign bits, respectively, for a first bits being concurrently processed by the first equalizer logic and a sign bit selection element to select between the first and second conditional sign bits based on the sign bit outcome of the first equalizer logic. The first and second pipelines compensate bits using compensation weights chosen using most recent first and second conditional sign bits and sign bit outcome.
