5.2.2.7. Pseudo Random Pattern Verifier

The Pseudo Random Pattern (PRP) verifier is available for 10GBASE-R and 10GBASE-R 1588 protocol modes. The PRP verifier block operates in conjunction with the descrambler. The PRP verifier monitors the output of the descrambler when block synchronization is achieved.

The rx_prbs_err error signal is shared between the PRBS checker and the PRP verifier.

The PRP verifier:

  • Searches for a test pattern (two local faults, or all 0s) or its inverse
  • Tracks the number of mismatches with a 16-bit error counter
