IDTCV122C PROGRAMMABLE FLEXPC CLOCK FOR P4 PROCESSOR COMMERCIAL TEMPERATURE RANGE PROGRAMMABLE FLEXPC CLOCK FOR P4 PROCESSOR IDTCV122C 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 KEY SPECIFICATION: • CPU/SRC CLK cycle to cycle jitter < 85ps • SATA CLK cycle to cycle jitter < 85ps • Static PLL frequency divide error = 0 ppm 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 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. Not recommended for new designs.
