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

• 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.
