Description

or DDR memory. It provides all necessary clock signals for such a system. The ICS9248-199 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 ICS9248-199 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  .1MHz increment.
