Features
• 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
• Uses external 14.318MHz crystal, no external load cap
required for CL=18pF crystal
• 48 pin 300 mil SSOP
