Document Table of Contents Programmable Differential On-Chip Termination (OCT)

The receiver buffer supports differential OCT resistances of 85, 100, 120, 150 Ω and OFF for GX channels. The receiver buffer of GT channels supports 100 Ω  differential termination only.

Note: The receiver OCT resistors have calibration support to compensate for process, voltage, and temperature (PVT) variations. This does not apply to GT devices.
