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]).
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 a 1333 MHz FSB frequency (selected by a 333 MHz
BCLK[1:0] frequency). Individual processors will only operate at their specified FSB
frequency.
For more information about these signals, refer to
platform design guidelines.
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
platform design guidelines for decoupling and routing guidelines.
