Pin Description
The ICS950602 is a single chip clock solution for VIA Mobile PL133T and PLE133T chipsets. It provides all necessar y clock
signals for such a system.
The ICS950602 is par t 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. 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. TCH also incorporates ICS'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. With
all these programmable features, ICS' TCH makes motherboard testing, tuning and improvement very simple.
