Electrical Specifications
3.1
Power and Ground Pins
For clean, on-chip power distribution, the processor will have a large number of V
CC
(power) and V
SS
(ground) inputs. All power pins must be connected to V
CC
power planes
while all V
SS
pins must be connected to system ground planes. Use of multiple power
and ground planes is recommended to reduce I*R drop. Please contact your Intel
representative for more details. The processor V
CC
pins must be supplied the voltage
determined by the VID (Voltage ID) pins.
3.2
FSB Clock (BCLK[1:0]) and Processor Clocking
BCLK[1:0] directly controls the FSB interface speed as well as the core frequency of the
processor. As in previous generation processors, the processor’s core frequency is a
multiple of the BCLK[1:0] frequency. The processor uses a differential clocking
implementation.
3.3
Voltage Identification
The processor uses seven voltage identification pins, VID[6:0], to support automatic
selection of power supply voltages. The VID pins for the processor are CMOS outputs
specifies the voltage level corresponding
to the state of VID[6:0]. A 1 in this refers to a high-voltage level and a 0 refers to low-
voltage level.
