Features:

• Supports Spread Spectrum modulation for CPU and

PCI clocks, default -0.4 downspread.

• Efficient Power management scheme through stop

clocks and power down modes.

• Uses external 14.318MHz crystal, no external load

cap required for CL=18pF crystal.

• 28-pin TSSOP package, 4.40mm (173mil).

Skew Characteristics:

• CPU – CPU <175ps

• PCI – PCI < 500ps

• CPU(early) – PCI = 1.5ns – 4ns.
