ICS94215 Datasheet, PDF (3/18 Pages) Integrated Circuit Systems – Programmable System Clock Chip for AMD - K7™ Processor

ICS94215
General Description
The ICS94215 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 ICS94215 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.
