ICS953002 is a 56-pin clock chip for P4 type processors with PCI-Express.
The ICS953002 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.
