Abstract:
An apparatus includes a plurality of phase detector circuits and a summing circuit. Each of the plurality of phase detector circuits may be configured to generate a phase up signal and a phase down signal in response to a respective pair of data samples and intervening transition sample. The summing circuit may be configured to generate an adjustment signal in response to the phase up and phase down signals of the plurality of phase detector circuits. A sum of the phase up signals and a sum of the phase down signals are weighted to provide a bias to a phase adjustment.
