ICS9248-56 Datasheet (Integrated Circuit Systems) - Frequency Generator & Integrated Buffers

ICS9248-56, Frequency Generator & Integrated Buffers

The ICS9248-56 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.
