General Description
The ICS9148-58 is the single chip clock solution for Desktop/Notebook designs using the VIA MVP3 style chipset. It provides all necessary clock signals for such a system.

FEATUREs
 • Generates the following system clocks:
    - 4 CPU(2.5V/3.3V) upto 100MHz.
    - 6 PCI(3.3V) @ 33.3MHz
    - 2AGP(3.3V) @ 2 x PCI
    - 12 SDRAMs(3.3V) @ either CPU or AGP
    - 2 REF (3.3V) @ 14.318MHz
 • Skew characteristics:
    - CPU - CPU<250ps
    - SDRAM - SDRAM < 250ps
    - CPU - SDRAM < 250ps
    - CPU(early) - PCI : 1-4ns
 • Spread Spectrum 0 to -5% down spread.
 • Serial I2C interface for Power Management, Frequency Select, Spread Spectrum.
 • Efficient Power management scheme through PCI and CPU STOP CLOCKS.
 • Uses external 14.318MHz crystal
 • 48 pin 300mil SSOP.
