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.
