Description

IDTCV104B  is a 48 pin clock generation device for desktop PC platforms. This chip of IDTCV104B incorporates four PLLs to allow independent generation of CPU, AGP/ PCI, SRC, and 48MHz clocks.  The dedicated PLL for Serial ATA clock provides high accuracy frequency.  IDTCV104B also implements Band-gap referenced IREF to reduce the impact of VDD variation on differential outputs, which can provide more robust system performance.
Static PLL frequency divide error of IDTCV104B can be as low as 36 ppm, providing high accuracy output clock.  Each CPU, AGP / PCI, SRC clock has its own Spread Spectrum selection.
