• Manufacturer Part Number: ics950410
• Description: Amd - K System Clock Chip
• Manufacturer: Integrated Device Technology

General Description
The ICS950410 is a main system clock solution for desktop designs using the AMD K8 CPU. It provides all necessary
clock signals for Clawhammer and Sledgehammer with AMD, VIA or ALI systems.
The ICS950410 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.
