ICS950812 Datasheet PDF - Integrated Circuit Systems

Recommended Application:
   CK-408 clock with Buffered/Unbuffered mode supporting Almador, Brookdale, ODEM, and Montara-G chipsets with PIII/P4 processor. Programmable for group to group skew.

Output Features:
• 3 0.7V Differential CPU Clock Pairs
• 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 5%
   and 10% over-clocked frequencies
• Supports spread spectrum modulation:
   No spread, Center Spread (±0.35%, ±0.5%,
   or ±0.75%), or Down Spread (-0.5%, -1.0%, or -1.5%)
• Offers adjustable PCI early clock via latch inputs
• Selectable 1X or 2X strength for REF via I2C interface
• 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.
