FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
IDTCV110Nisa56pinclockdevice,compliantwithIntelCK410specifications.
The CPU output buffer is designed to support up to 400MHz processor. This
chip has three PLLs inside for CPU/SRC/PCI, SATA, and 48MHz/DOT96 IO
clocks. One dedicated PLL for Serial ATA clock provides high accuracy
frequency. This device also implements Band-gap referenced IREF to reduce
theimpactofVDDvariationondifferentialoutputs,whichcanprovidemorerobust
systemperformance.
Each CPU/SRC/PCI, SATA clock has its own Spread Spectrum selection,
which allows for isolated changes instead of affecting other clock groups.
OUTPUTS:
2*0.7V current –mode differential CPU CLK pair
6*0.7V current –mode differential SRC CLK pair, one dedicated
for SATA
One CPU_ITP/SRC selectable CLK pair
9*PCI, 3 free running, 33.3MHz
1*96MHz, 1*48MHz
1*REF
KEY SPECIFICATIONS:
CPU/SRC CLK cycle to cycle jitter < 85ps
SATA CLK cycle to cycle jitter < 85ps
PCI CLK cycle to cycle jitter < 250ps
