VSS_MB_
REGULATION

Output

This land is provided as a voltage regulator feedback sense point for 
V

SS

. It is connected internally in the processor package to the sense 

point land V27 as described in the Voltage Regulator-Down (VRD) 
10.1 Design Guide for Desktop Socket 775.

VTT

Miscellaneous voltage supply.

VTT_OUT_LEFT

VTT_OUT_RIGHT

Output

The VTT_OUT_LEFT and VTT_OUT_RIGHT signals are included to 
provide a voltage supply for some signals that require termination to 
V

TT

 on the motherboard. 

VTT_SEL

Output

The VTT_SEL signal is used to select the correct V

TT

 voltage level for 

the processor. This land is connected internally in the package to 
V

TT

.

VTTPWRGD

Input

The processor requires this input to determine that the V

TT

 voltages 

are stable and within specification.
