94230BF

PC MAIN CLOCK
General DescriptionThe ICS94230 is a main clock synthesizer chip for AMD-K7 based systems with VIA KT266 style chipset. This providesall clocks required for such a system.The ICS94230 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.
