  • International Classification:
    H04L 7/00
    H04L 7/02
    H04B 1/16
    H03L 7/08
  • Abstract:
    Embodiments include systems and methods for improving link performance and tracking capability of a baud-rate clock data recovery (CDR) system using transition pattern detection. For example, a multi-level signal is received via a data channel and converted to a pseudo-NRZ signal. CDR early/late voting can be derived from the converted (baud-rate) pseudo-NRZ signal and from error signals from the received PAM4 signal, and the voting can be implemented with different phase error detector (PED) functional approaches. Different approaches can yield different CDR performance characteristics and can tend to favor different PAM4 transition patterns. Embodiments can identify jittery patterns for a particular CDR implementation and can add features to the CDR to filter out those patterns from being used for CDR early/late voting.

  • International Classification:
    H04L 25/03
    H04L 12/825
  • Abstract:
    Embodiments include systems and methods for implementing a multi-rate FIR by using rate-dependent bit stuffing on the cursor, while using rate-independent (e.g., full-rate) spacing on the pre- and post-cursor. For example, in the FIR data path, the cursor bit output is generated using bit stuffing, depending on a selected rate mode (e.g., full-rate, half-rate, quarter-rate, eighth-rate, etc.), but the spacing of the pre-cursor, cursor, and post-cursor are maintained at 1 UI apart (i.e., the full-rate spacing) for all rate modes. Such an approach can appreciably reduce complexity of the logic and can appreciably relieve the critical timing path.
