Description
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
VTTPWRGD
Output
Input
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.
The processor requires this input to determine that the V_TT voltages
are stable and within specification.
