DESCRIPTION:

IDTCV122C 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 referencedIREF to reduce the impact ofVDD 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.

FEATURES:

• One high precision N Programming PLL for CPU

• One high precision N Programming PLL for SRC/PCI

• One high precision PLL for SATA

• One high precision PLL for 96MHz/48MHz

• Band-gap circuit for differential outputs

• Support multiple spread spectrum modulation, down and center

• Support I2C block read/write, index read/write

• Selectable output strength for REF, PCI, and 48MHz

• Available in SSOP package
