ICS950508

0470E—04/06/05

Pin Description

The ICS950508 is a single chip clock solution for desktop designs using the 810/810E, 815 and 815 B-Step style chipset. It

provides all necessary clock signals for such a system.

The ICS950508 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 offers 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 and a reset feature to provide a safe setting

under unstable system conditions. M/N control can configure output frequency with resolution up to 0.1MHz increment. With

all these programmable features ICS's, TCH makes mother board testing, tuning and improvement very simple.
