IDTCV115-2 is a 56 pin clock device, complying the latest Intel CK410 requirements, for Intel advance P4 processors. The CPU output buffer is designed to support up to 400MHz processor. One dedicated PLL for Serial ATA clock provides high accuracy frequency. This device also implements Band-gap referenced IREF to reduce the impact of VDD variation on differential outputs, which can provide more robust system performance. Each CPU/SRC/PCI, SATA clock has its own Spread Spectrum selection, which allows for isolated changes instead of affecting other clock groups.
