Reference and Compensation Pins
The 41210 Bridge has one reference pin and three compensation pins:
• PE_RCOMP[1:0] are two separate pins that provide voltage compensation for the PCI
Express interface on the 41210 Bridge. The nominal compensation voltage is 0.5V. An
external 24.9 ±1% pull-up resistor should be used to connect to VCC15. A single pull-up
resistor can be used to for both of these signals.
