W164, Spread Spectrum Desktop/Notebook System Frequency Generator

CPU Clock Outputs 0 through 1: These two CPU clocks run at a frequency set by SEL100/66#.

Output voltage swing is set by the voltage applied to VDDQ2.

PCI Clock Outputs 1 through 6 and PCI_F: These seven PCI clock outputs run synchronously to the CPU clock.

Voltage swing is set by the power connecti
