IDTCV115-4 PROGRAMMABLE FLEXPC CLOCK FOR P4 PROCESSOR COMMERCIAL TEMPERATURE RANGE PROGRAMMABLE FLEXPC CLOCK FOR P4 PROCESSOR IDTCV115-4 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 48MHz • Band-gap circuit for differential outputs • Support multiple spread spectrum modulation, down and center • Support SMBus block read/write, index read/write • Selectable output strength for REF, PCI, and 48MHz • Available in SSOP package DESCRIPTION: IDTCV115-4 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.
