General Description
The ICS9248-50 is the Main clock solution for Notebook designs using the Intel 440BX style chipset. Along with an SDRAM buffer such as the ICS9179-03, it provides all necessary clock signals for such a system.

Features
• Generates the following system clocks:
    - 2 CPU (2.5V) up to 100MHz.
    - 6 PCI (3.3V) @ 33.3MHz (Includes one free running).
    - 2 REF clks (3.3V) at 14.318MHz.
• Skew characteristics:
    - CPU – CPU<175ps
    - PCI – PCI < 500ps
    - CPU(early) – PCI = 1.5ns – 4ns.
• Supports Spread Spectrum modulation for CPU and PCI clocks, 0.5% down spread
• Efficient Power management scheme through stop clocks and power down modes.
• Uses external 14.318MHz crystal, no external load cap required for CL=18pF crystal.
• 28-pin (209 mil) SSOP and (6.1mm) TSSOP package
