ICS94241

0453C—10/26/04

Pin Configuration

Notes:

1:

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

2:

Internal Pull-down to GND on indicated inputs

3:

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.

General Description

The ICS94241 is a single chip timing control hub for desktop designs using VIA PL133-T style chipset with Intel

differential PIII processor. It provides all necessary clock signals for such a system.

The ICS94241 is part of a whole new line of ICS clock generators and buffers called TCH™

(Timing Control Hub).

ICS is the first to introduce a whole product line which offers full programmability and flexibility on a single clock

device. This part incorporates ICS's newest clock technology which more robust features and functionality.

Employing the use of a serially programmable I

2C interface, this device can adjust the output clocks by

configuring the frequency setting, the output divider ratios, selecting the ideal spread percentage, the output

skew, the output strength, and enabling/disabling each individual output clock. TCH also incorporates ICS's

Watchdog Timer technology in having a frequency reset feature to provide a safe setting under unstable system

conditions.
