Datasheet
NOTES:
1. Intel Xeon processors only support BR0# and BR1#. However, the Intel Xeon processors must terminate
BR2# and BR3# to the processor VCC..
VCCSENSE
VSSSENSE
O
The Vccsense and Vsssense pins are the points for which processor minimum and
maximum voltage requirements are specified. Uniprocessor designs may utilize
these pins for voltage sensing for the processor's voltage regulator. However, multi-
processor designs must not connect these pins to sense logic, but rather utilize
them for power delivery validation
.
VID[4:0]
O
VID[4:0] (Voltage ID) pins can be used to support automatic selection of power
supply voltages (VCC). Unlike previous generations of processors, these are logic
signals and are driven by the Intel Xeon processor MP on the 0.13 micron process
processor. Hence the voltage supply for these pins (SM_Vcc) must be valid before
the VRM supplying Vcc to the processor is enabled (see Figure ). Conversely, the
VRM output must be disabled prior to the voltage supply for these pins becomes
invalid. The VID pins are needed to support processor voltage specification
variations. See Table 4 for definitions of these pins. The power supply must supply
the voltage that is requested by these pins, or disable itself.
VSSA
I
VSSA provides an isolated, internal ground for internal PLL’s. Do not connect
directly to ground. This pin is to be connected to VCCA and VCCIOPLL through a
discrete filter circuit. Follow the guidelines for VSSA (Section 2.5). Refer to the
appropriate platform design guidelines for complete implementation details.
