Electrical Specifications
The power pod provides a selectable output voltage controlled via multiple binary weighted
Voltage Identification (VID) inputs. The VID value (high = 1; low = 0) is defined in
Table 2-23 .
VID pads shall be considered as LVTTL inputs to the power pod, having resistive pull-ups (5 k
Ω
)
included inside the power pod to the internal 3.3 V power supply. The VID pads on the power
connector tab will be pulled low with 10
Ω
resistors that are internal to the processor. The 10
Ω
resistive pulldowns are controlled by Intel and will not be externally adjustable.
The processor has several power levels as shown in Table 2-24 and in Figure 2-5 . Full power to the
processor is defined in Table 2-2 .
