ICS94228
0447E—05/07/04
General Description
The ICS94228 is a main clock synthesizer chip for AMD-K7 based systems with VIA style chipset. This provides all
clocks required for such a system.
The ICS94228 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.
SRESET# Signal Description
The SRESET# signal from ICS94228 system clock generator is a real time active low pulse that can be used to reset
the system.
The Open-Drain Nch output Reset# pin needs to be tied to the system reset line which has a pull-up resistor. When
activated, the SRESET# output will be driven to a low with a 32ms pulse width.
