Electrical Specifications
2.8.2
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 800 MHz FSB frequency (selected by a 200 MHz 
BCLK[1:0] frequency). Individual processors will only operate at their specified FSB 
frequency. 
2.8.3
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.
