ICS9248-61 Overview
The ICS9248-61 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. Spread spectrum may be enabled by driving pin 26, SPREAD# active (Low) at power-on.
ICS9248-61 Key Features
- 2CPU(2.5V) up to 100MHz
- 7 PCI(3.3V) @ 33.3MHz (Includes one free running)
- 2 REF clks Fixed (3.3V) 48MHz at 14.318MHz. Skew characteristics
