ICS94206

General Description

Pin Configuration

The ICS94206 is a single chip clock solution for desktop designs using the BX/Apollo Pro133/ALI 1631 style chipset. It provides all

necessary clock signals for such a system.

The ICS94206 belongs to ICS new generation of programmable system clock generators. It employs serial programming I

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.

Notes:

1:

Internal Pull-up Resistor of 120K to 3.3V on indicated inputs

2:

Bidirectional input/output pins, input logic levels are latched at internal power-on-reset. Use 10Kohm resistor

to program logic Hi to VDD or GND for logic low.
