General Description
Pin Configuration
The
ICS94209
is a single chip clock solution for desktop
designs using 630S chipsets. It provides all necessary clock
signals for such a system.
The
ICS94209
belongs to ICS new generation of
programmable system clock generators. It employs serial
programming I
2
C 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 becomes unstable from over
clocking.
