7.17. Loading IP Configuration Settings

You may need to set the PMA RX adaptation settings for optimal transceiver performance. See the PMA Tuning for more information. There are two methods for setting the PMA RX adaption values.

  • The first method is to use PMA attributes to load the PMA RX adaptation settings one by one. See PMA Attribute Codes and Configuring a PMA Parameter Tunable by the Adaptive Engine for details of how to load an adaptation setting.
  • The second method is, when you generate the IP, to define up to eight different PMA configurations in the Native PHY IP to use built-in logic to load one of them to all transceiver channels in the instance at run-time. See Loading IP Configuration Settings Process for more details and Configuring a PMA Parameter Using Native PHY IP for an example.
