The ICS952011 is a two chip clock solution for desktop designs using SIS 645/645DX/648/650 style chipsets. When used with a zero delay buffer such as the ICS9179-16 for PC133 or the ICS93735 for DDR applications it provides all the necessary clocks signals for such a system. The ICS952011 is part of a whole new line of ICS clock generators and buffers called TCH™ (Timing Control Hub). ICS is the first to introduce a whole product line which offers full programmability and flexibility on a single clock device. 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.

TCH also incorporates ICS's Watchdog Timer technology and a reset feature of the ICS952011 to provide a safe setting under unstable system conditions. M/N control can configure output frequency with resolution up to 0.1MHz increment.
