Word Aligner and BitSlip Parameters

The word aligner aligns the data coming from RX PMA deserializer to a given word boundary. When the

word aligner operates in bitslip mode, the word aligner slips a single bit for every rising edge of the bit slip

control signal.
Note: For more information refer to the Word Aligner section in the Transceiver Architecture in Arria V

Devices.
