DMI_TXP[3:0] 
DMI_TXN[3:0]

DMI output to Intel NM10 Express Chipset: Direct 
Media Interface transmit differential pair.

EXP_ICOMPI

PCI Express-G Input Current Compensation. Connect 
to a 50-Ohm resistor to ground. EXP_ICOMPI and 
EXP_RCOMPO are shorted off-die and should be 
connected to the same 50-Ohm resistor.

Analog

EXP_RCOMPO

PCI-Express-G Resistance Compensation. Connect to a 
50-Ohm resistor to ground. EXP_ICOMPI and 
EXP_RCOMPO are shorted off-die and should be 
connected to the same 50-Ohm resistor.
