SIS 645/650 style chipsets.

The IDT952001 is a two chip clock solution for desktop designs using SIS 645/650 style chipsets. When used with a zero delay buffer such as the IDT9179-06 for PC133 or the IDT93705 for DDR applications it provides all the necessary clocks signals for such a system. The IDT952001 is part of a whole new line of IDT clock generators and buffers called TCH™ (Timing Control Hub). IDT 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 IDT’s Watchdog Timer technology and a reset feature to provide a safe setting under unstable system conditions. M/N control can configure output frequency with resolution up to 0.1MHz increment.
