6.10. Changing Analog PMA Settings
The PMA analog settings can be broadly divided into the following groups:
- PMA analog settings that are channel or system dependent:
- These settings may vary from channel to channel based on channel loss or other factors
- You can set these PMA analog settings based on IBIS-AMI or Advanced Link Analyzer simulations
-
Settings under this category include: VOD, TX pre-emphasis, VGA, CTLE, DFE
Refer to the Logical View of the L-Tile/H-Tile Transceiver Registers for the attribute names and addresses of the relevant registers for reconfiguration.
- PMA analog settings that are transceiver protocol-type, data rate dependent, or both:
- These settings may vary for each transceiver protocol-type, data rate, or both in your design. You can set these PMA Analog settings using direct reconfiguration flow by performing RMWs to the respective registers of each channel (OR).
- These are important to reconfigure when changing datarates.
- Settings under this category include: slew rate, equalizer bandwidth, compensation enable.
Refer to the Logical View of the L-Tile/H-Tile Transceiver Registers for the attribute names and addresses of the relevant registers for reconfiguration.
