General Description
The ICS9148-75 generates all clocks required for high speed RISC or CISC microprocessor systems such as Intel PentiumPro™, AMD™ or Cyrix™. Sixteen different reference frequency multiplying factors are externally selectable with smooth frequency transitions.

FEATUREs
• Generates the following system clocks:
    - 3 CPU(2.5V/3.3V) up to 100MHz.
    - 6 PCI(3.3V) @ 33.3MHz (including one free running PCICLK)
    - 3AGP(3.3V) @ 2 x PCI
    - 13 SDRAMs(3.3V) up to 100MHz
    - 1 REF (3.3V) @ 14.318MHz
    - 1 - 48MHz (3.3V) fixed
• Skew characteristics:
    - CPU – CPU<250ps
    - CPU(early) – PCI : 1-4ns
    - AGP – PCI: 250ps
    - PCI – PCI <500ps
• Supports Spread Spectrum modulation & I2C programming for Power Management, Frequency Select
• Efficient Power management scheme through power down PCI, AGP and CPU_STOP clocks.
• Uses external 14.318MHz crystal
• 48 pin 300mil SSOP.
