The receiver buffer has on-chip biasing circuitry to establish the required VCM at the receiver input.

The Quartus® Prime software automatically chooses the optimal setting for RX VCM.


On-chip biasing circuitry is available only if you select OCT. If you select external termination, you must implement off-chip biasing circuitry to establish the VCM at the receiver input buffer.

Manual VCM adjustment is not supported and is only adjusted by calibrations.
