Abstract:
Various embodiments of the present invention provide systems and methods for improved timing recovery. As one example, some embodiments of the present invention provide timing recovery circuits that include an error signal and a digital phase lock loop circuit. The error signal indicates a difference between the predicted sample time and an ideal sample time. The digital phase lock loop is operable to apply an adjustment value such that a subsequent sample time is moved toward the ideal sample time. Further, the digital phase lock loop circuit includes an adjustment limit circuit that is operable to limit the adjustment value.
