Description

PC CLOCK
IDTCV123 is a 56 pin clock device. The CPU output buffer is designed tosupport up to 400MHz processor. CV123PV has three PLLs inside for CPU/SRC/PCI, SATA, and 48MHz/DOT96 IO clocks. One dedicated PLL for SerialATA clock provides high accuracy frequency. CV123PV also implementsBand-gap referenced IREF to reduce the impact of VDD variation on differentialoutputs, which can provide more robust system performance.Static PLL frequency divide error can be as low as 36 ppm, worse case 114ppm, providing high accuracy output clock. Each CPU/SRC/PCI, SATA clockhas its own Spread Spectrum selection, which allows for isolated changesinstead of affecting other clock groups.
