General Description
The ICS9169C-40 is a Clock Synthesizer chip for Pentium or Cyrix CPU based motherboards using PCI.
Features include eight CPU clocks and six PCI clocks. A Reference Output is available equal to the crystal frequency. The device meets the Pentium power-up stabilization, which requires that CPU and PCI clocks be stable within 2ms after power-up.

FEATUREs
• 8 selectable CPU clocks up to 75MHz
• Six synchronous PCI clocks
• One Referance Clock at 14.318MHz
• Power-up stabilization time = 2ms on all CPU and PCI clocks, which meets Intel PentiumPro power-up
• Low CPU and PCI clock jitter <500ps
• Low skew output
• Improved output drivers are designed for low EMI
• Test Mode
• Optional common or mixed supply mode:
    (VDD = VDDL1 =VDDL2 = 3.3V)
    (VDD = 3.3V,VDDL1=VDDL2 = 2.5)
    (VDD = 3.3V, VDDL1 = 3.3V, VDDL2 = 2.5V)
• Space saving and low cost 34-pin SSOP package
