General Description
The ICS94225 is a main clock synthesizer chip for AMD-K7 based systems with AMD 750/760 style chipsets. This
provides all clocks required for such a system.
The ICS94225 belongs to ICS new generation of programmable system clock generators.
It employs serial
programming I
2C 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.
