General Description
The ICS950402 is a main system clock solution for desktop designs using the AMD K8 CPU. It provides all necessary
clock signals for Clawhammer and Sledgehammer systems.
The ICS950402 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
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.
