5.3.2.1. Word Aligner

The word aligner receives the serial data from the PMA and realigns the serial data to have the correct word boundary according to the word alignment pattern configured. This word alignment pattern can be 7, 8, 10, 16, 20, 32 and 40 bits in length.

Depending on your PCS-PMA interface width, the word aligner can be configured in one of the following modes:

  • Bit slip
  • Manual alignment
  • Synchronous state machine
  • Deterministic latency
