General Description

The ICS950905 is a single chip clock solution for desktop designs using the VIA P4X266 chipset with PC133 or DDR memory.

with PC133 or DDR memory. When used with a fanout buffer such as the ICS93712, ICS93715 or the ICS93718 provides all

the necessary clock signals for such a system.

The ICS950905 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 I2

C 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.
