VID_SELECT

O

VID_SELECT is an output from the processor which selects the 

appropriate VID table for the Voltage Regulator. This signal is not 

connected to the processor die. This signal is a no-connect on the 

Dual-Core Intel® Xeon® Processor 5200 Series package.

VSS_DIE_SENSE
VSS_DIE_SENSE2

O

VSS_DIE_SENSE and VSS_DIE_SENSE2 provides an isolated, low 

impedance connection to the processor core power and ground. This 

signal should be connected to the voltage regulator feedback signal, 

which insures the output voltage (that is, processor voltage) remains 

within specification. Please see the applicable platform design guide 

for implementation details.

VTT

P

The FSB termination voltage input pins. Refer to 

 for 

further details.

VTT_OUT

O

The VTT_OUT signals are included in order to provide a local V

TT

 for 

some signals that require termination to V

TT

 

on the motherboard.

VTT_SEL

O

The VTT_SEL signal is used to select the correct V

TT

 voltage level for 

the processor. VTT_SEL is connected to VSS on the Dual-Core Intel® 

Xeon® Processor 5200 Series package.
