When designing for the PCB, refer to Video PHY Controller LogiCORE IP Product Guide (PG230) for pin outputs to the PCB from the PHY. This section discusses the pin outputs from the subsystem and external IC/PCB considerations.
Pins
The following pins need to be driven through a level shifter, such as the SN74AVC4T774, followed by a line driver, such as the SN64MLVD2020A, and then an RC circuit to meet the DisplayPort standard requirements. See the DisplayPort standard for more information on switching requirements.

The following pins are detailed in Video PHY Controller LogiCORE IP Product Guide (PG230), but AMD recommends sending these through a redriver, such as the SN65DP141, to simplify compliance testing.
