1.2.1.3. Programmable VCM

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

The Quartus II software automatically chooses the best VCM setting.

Note: On-chip biasing circuitry is available only if you select one of the Termination logic options to configure OCT. If you select external termination, you must implement off-chip biasing circuitry to establish the VCM at the receiver input buffer.
