Configure the modes using one of the following methods:

Method 1 - Using Cyclone® 10 GX Transceiver Native PHY IP Core

  1. Select the CTLE mode in the RX PMA tab of the PHY IP Core
  2. Compile the design
  3. If the CTLE is in Manual mode, set the CTLE gain value using the assignment editor/Quartus Settings File (.qsf). Then, recompile the design to make these values effective.

    Refer to Analog Parameter Settings for more details about Receiver Equalization Settings.

Method 2 - Using AVMM Interface

  1. Any changes you make using AVMM interface take precedence over what was configured in Native PHY IP GUI or Assignment Editor.
    1. For CTLE in Manual mode, set the CTLE gain value using the reconfiguration interface. The values are written dynamically and do not require design re-compilation.

      Refer to Intel® Cyclone® 10 GX Register Map for details on the specific registers that set the CTLE gain values.

    Note: You must set VGA manually for all combinations of CTLE mode.
