ICS952702
General Description
The ICS952702 is a two chip clock solution for desktop designs using SIS 746 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 ICS952702 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 to provide a safe setting
under unstable system conditions. M/N control can configure output frequency with resolution up to 0.1MHz increment.
