Electrical Specifications

Dual-Core Intel® Xeon® Processor 3000 Series Datasheet

2.7.6

FSB Frequency Select Signals (BSEL[2:0])

The BSEL[2:0] signals are used to select the frequency of the processor input clock
(BCLK[1:0]).

Table 2-17

defines the possible combinations of the signals and the

frequency associated with each combination. The required frequency is determined by
the processor, chipset, and clock synthesizer. All agents must operate at the same
frequency.

The Dual-Core Intel

Xeon

processor 3000 series operates at a 1066 MHz FSB

frequency (selected by a 266 MHz BCLK[1:0] frequency).

2.7.7

Phase Lock Loop (PLL) and Filter

An on-die PLL filter solution will be implemented on the processor. The VCCPLL input is
used for the PLL. Refer to

Table 2-4

for DC specifications.
