ICS9148F-37-T Datasheet PDF - Integrated Circuit Systems

General Description
The ICS9148-37 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 - AGP: ≤ 1ns
    - CPU(early) - PCI : 1-4ns
• Supports Spread Spectrum modulation ±0.25, ±0.6%
• 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.
