Receiver On-Chip Termination


Controls the on-chip RX differential termination. For data rates higher than 25 Gbps, set the termination resistance to 85 Ohm.

Note: For protocols such as QPI, you need to set the termination setting to R_R2. For all the other protocols, you can either set this setting to R_R1 or R_R2. The default value set for all the protocols other than QPI depends upon the data rate. When the data rate is less than or equal to 17.4 Gbps, the de
