Type
This input should be left as a no connect in order for the processor
Input to boot. The processor will not boot on legacy platforms where this
land is connected to V
VSS are the ground pins for the processor and should be connected
Input
to the system ground plane.
Input VSSA is the isolated ground for internal PLLs.
VSS_SENSE is an isolated low impedance connection to processor
Output core V . It can be used to sense or measure ground near the
SS
silicon with little noise.
This land is provided as a voltage regulator feedback sense point for
V . It is connected internally in the processor package to the sense
SS
Output point land V27 as described in the Voltage Regulator-Down (VRD)
11.0 Processor Power Delivery Design Guidelines For Desktop
LGA775 Socket.
Input Miscellaneous voltage supply.
The VTT_OUT_LEFT and VTT_OUT_RIGHT signals are included to
Output provide a voltage supply for some signals that require termination
to V on the motherboard.
TT
The VTT_SEL signal is used to select the correct V
Output the processor. This land is connected internally in the package to
V .
