ICS952702
0795D—05/06/05
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 I
2C 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.
