NOTES:
1.
Individual processors operate only at or below the rated frequency.
2.
Listed frequencies are not necessarily committed production frequencies.
2.7.2
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]). 
 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 processor will operate at an 1066 MHz FSB frequency (selected by a 266 MHz 
BCLK[1:0] frequency). Individual processors will only operate at their specified FSB 
frequency.
For more information about these signals, refer to 
2.7.3
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 
 for DC specifications.
