ICS9248-61 Datasheet (Renesas) - Frequency Timing Generator

ICS9248-61, Frequency Timing Generator

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.
