General Description
The ICS950908 is a single chip clock solution for desktop designs using the VIA Pro266/PN266/CLE266/CM400 chipset with
PC133 or DDR memory.
The ICS950908 is part of a whole new line of ICS clock generators and buffers called TCH™ (Timing Control Hub). 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. M/N control can configure output frequency with resolution up to 0.1MHz increment.
