? Generates system clocks for CPU, IOAPIC, PCI, plus
14.314 MHz REF (0:2), USB, and Super I/O
? Supports single or dual processor systems
? Supports Spread Spectrum modulation for CPU & PCI
clocks, down spread -0.5
? Skew from CPU (earlier) to PCI clock (rising edges for
100/33.3MHz) 1.5 to 4ns
? Two fixed outputs at 48MHz.
? Separate 2.5V and 3.3V supply pins
? 2.5V or 3.3V output: CPU, IOAPIC
? 3.3V outputs: PCI, REF, 48MHz
? No power supply sequence requirements
