Adaptive pattern filtering for clock and data recovery to minimize interaction with decision feedback equalization

Systems and methods disclosed herein provide for adaptively applying pattern filters so that the edges are discarded only when the DFE feedback has adapted to levels that can corrupt the timing recovery. Embodiments of the systems and methods provide for a phase detector that selectively suppresses...

Zusammenfassung:Systems and methods disclosed herein provide for adaptively applying pattern filters so that the edges are discarded only when the DFE feedback has adapted to levels that can corrupt the timing recovery. Embodiments of the systems and methods provide for a phase detector that selectively suppresses timing information based on the logic level states of the Qp and Qm data samples associated with the received signal.
