5.1.5.2. Programmable Differential On-Chip Termination (OCT)

Receiver buffers include programmable on-chip differential termination of 85Ω, 100Ω, or OFF.

You can disable OCT and use external termination. If you select external termination, the receiver common mode is tri-stated. Common mode is based on the external termination connection. You also need to implement off-chip biasing circuitry to establish the VCM at the receiver buffer.
