Programmable Timing Control Hub™ for P4™

Frequency Generator with 200MHz Differential CPU Clocks

IDT952601 follows Intel CK409 Yellow Cover specification. This clock synthesizer provides a single chip solution for next generation P4 Intel processors and Intel chipsets. IDT952601 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 support.

IDT952906A is a 48 pin clock chip for VIA VN800/CN700/P4M800 style chipsets. When used with a fanout DDR buffer, suchas the 93788, it provides all the necessary clock signals for such a system.The IDT952906A is part of a whole new line of IDT clock generators and buffers called TCH™ (Timing Control Hub). This partincorporates IDT's newest clock technology which offers more robust features and functionality. Employing the use of aserially programmable I2C interface, this device can adjust the output clocks by configuring the frequency setting, the outputdivider ratios, selecting the ideal spread percentage, the output skew, the output strength, and enabling/disabling eachindividual output clock. M/N control can configure output frequency with resolution up to 0.1MHz increment.

The 952926 is a 48-pin clock chip for VIA VX/CX 700 style chipsets.

953002 is a 56-pin clock chip for P4 type processors with PCI-Express. The 953002 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.

IDT954101 follows Intel CK410 Yellow Cover specification. This clock synthesizer provides a single chip solution for next generation P4 Intel processors and Intel chipsets. IDT954101 is driven with a 14.318MHz crystal. It generates CPU outputs up to 400MHz. It also provides a tight ppm accuracy output for Serial ATA and PCI-Express support
