General Description
The ICS950218 is a single chip clock solution for desktop designs using the Intel Brookdale chipset with PC133 or DDR
memory. It provides all necessary clock signals for such a system.
The ICS950218 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
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.
