DESCRIPTION:

IDTCV152 is a 56 pin clock device, compliant with Intel CK410B specification.The CPU output buffer is designed to support up to 400MHz processor. This chip has three PLLs inside for CPU, SRC/PCI, and 48MHz IO clocks. This device also implements Band-gap referenced IREF to reduce the impact of VDDvariation on differential outputs, which can provide more robust system performance. Each CPU and SRC/PCI has its own Spread Spectrum selection, which allows for isolated changes instead of affecting other clock groups.

FEATURES:

• One high precision PLL for CPU, SSC, and N programming

• One high precision PLL for SRC/PCI, SSC, and N programming

• One high precision PLL for 48MHz

• Band-gap circuit for differential outputs

• Support spread spectrum modulation, down spread 0.5 and others

• Support SMBus block read/write, index read/write

• Selectable output strength for REF, 48MHz, PCI

• Allows for CPU frequency to change to a higher frequency for maximum system computing power

• Available in SSOP and TSSOP packages
