ICS94222

The ICS94222 is a single chip clock solution for desktop designs using the BX/Apollo Pro133/ALI 1631 style chipset. It provides all necessary clock signals for such a system.

The ICS94222 belongs to ICS new generation of programmable system clock generators. It employs serial programming I²C interface as a vehicle for changing output functions, changing output frequency, configuring output strength, configuring output to output skew, changing spread spectrum amount, changing group divider ratio and dis/enabling individual clocks. This device also has ICS propriety 'Watchdog Timer' technology which will reset the frequency to a safe setting if the system become unstable from over clocking.
