FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
IDTCV119E is a 48 pin clock generation device for desktop PC platforms.
This chip 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. This device also implements Band-gap
referenced I
REF
to reduce the impact of V

variation on differential outputs,
which can provide more robust systemperformance.
Static PLL frequency divide error can be as low as 36 ppm providing high
accuracy output clock. Each CPU, AGP/PCI, SRC clock has its own Spread
Spectrumselection.
K EY SPECIFICATION:
CPU/SRC CLK cycle to cycle jitter < 125ps
SATA CLK cycle to cycle jitter < 125ps
PCI CLK cycle to cycle jitter < 250ps
Static PLL frequency divide error as low as 36 ppm
