Preliminary Product Preview
0640D—12/30/03
The ICS950219 is a single chip clock solution for desktop designs using the Intel 845 chipset with PC133 or DDR memory. It
provides all necessary clock signals for such a system.
The ICS950219 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.
