In described embodiments, a method for producing sample decisions with a digital signal processing-based SERDES device includes converting an analog signal to a digital signal, equalizing the digital signal, selecting inputs for a phase detector in a main CDR loop, computing a phase difference signal, producing a phase skew to signals for a last equalization stage by a first interpolation filter bank, generating a control signal to control the phase provided by the first interpolation filter bank by a phase skew adaptation loop, and updating the phase skew values to generate a resulting decision. A device includes a first interpolation filter bank inserted between the equalization stages is configured to generate phase skew signals to a last equalization stage and a phase skew loop responsive to the last equalization stage is configured to adjust the phase skew provided by the first interpolation filter bank.
