Type
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.
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.
P The FSB termination voltage input pins. Refer to
further details.
O The VTT_OUT signals are included in order to provide a local V
some signals that require termination to V
O The VTT_SEL signal is used to select the correct V
the processor. VTT_SEL is connected to VSS on the Dual-Core Intel®
Xeon® Processor 5200 Series package.
