Systems, Inc.

General Description

ICS952607 is a 48 pin clock chip following Intel CK409 Yellow Cover specification. This clock synthesizer provides a single

chip solution for next generation P4 Intel processors and Intel chipsets. ICS952607 is driven with a 14.318MHz crystal. It

generates CPU outputs up to 200MHz. It also provides a tight ppm accuracy output for Serial ATA suuport.

The ICS952607 is part of a whole new line of ICS clock generators and buffers called TCH™ (Timing Control Hub). 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. M/N control can configure output frequency with resolution up to 0.1MHz increment. This part also

provides 128 frequency selections via ICS QuadROM^TMtechnology as an alternate to M/N programming.
