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
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. M/N control can configure output frequency with resolution up to 0.1MHz increment.
