Programmable Timing Control Hub™ For P4™

The 950211 is a single chip clock solution for desktop designs using the Intel Brookdale chipset with PC133 or DDR memory. It provides all necessary clock signals for such a system. The 950211 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 I2C 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.
