Recommended Application:
   CK-408 clock for Brookdale/Odem/Montara-GM for P4/Banias
   processor.

Output Features:
• 3 Differential CPU Clock Pairs @ 3.3V
• 7 PCI (3.3V) @ 33.3MHz including 2 early PCI clocks
• 3 PCI_F (3.3V) @ 33.3MHz
• 1 USB (3.3V) @ 48MHz, 1 DOT (3.3V) @ 48MHz
• 1 REF (3.3V) @ 14.318MHz
• 5 3V66 (3.3V) @ 66.6MHz
• 1 VCH/3V66 (3.3V) @ 48MHz or 66.6MHz

FEATUREs:
• Provides standard frequencies and additional 3%, 5%
   and 10% over-clocked frequencies
• Supports spread spectrum modulation:
   No spread, Center Spread (±0.3%, ±0.55%), or Down
   Spread (-0.5%, -0.75%)
• Offers adjustable PCI early clock via latch inputs
• Selectable 1X or 2X strength for REF via I2C interface
• Programmable group to group skew
• Linear programmable frequency and spreading %
• Efficient power management scheme through PD#,
   CPU_STOP# and PCI_STOP#.
• Uses external 14.318MHz crystal
• Stop clocks and functional control available through
   I2C interface.
