9DBV0841
DATASHEET
Description
The 9DBV0841 is a 1.8V member of IDT's full featured PCIe
family. It has integrated output terminations providing
Zo=100 for direct connection for 100 transmission lines.
The device has 8 output enables for clock management and 3
selectable SMBus addresses.
Recommended Application
SSD, microServers, WLAN Access points
Output Features
• 8 – 1-200Hz Low-Power (LP) HCSL DIF pairs
Key Specifications
• DIF cycle-to-cycle jitter <50ps
• DIF output-to-output skew <50ps
• DIF additive phase jitter is <100fs rms for PCIe Gen3
• DIF additive phase jitter <300fs rms for 12k-20MHz
Block Diagram
Features/Benefits
• LP-HCSL outputs save 32 resistors; minimal board space
and BOM cost
• 62mW typical power consumption in PLL mode; eliminates
thermal concerns
• Spread Spectrum (SS) compatible; allows use of SS for
EMI reduction
• OE# pins; support DIF power management
• HCSL compatible differential input; can be driven by
common clock sources
• Programmable Slew rate for each output; allows tuning for
various line lengths
• Programmable output amplitude; allows tuning for various
application environments
• Pin/software selectable PLL bandwidth and PLL Bypass;
minimize phase jitter for each application
• Outputs blocked until PLL is locked; clean system start-up
• Software selectable 50MHz or 125MHz PLL operation;
useful for Ethernet applications
• Configuration can be accomplished with strapping pins;
SMBus interface not required for device control
• 3.3V tolerant SMBus interface works with legacy controllers
• Space saving 48-pin 6x6mm VFQFPN; minimal board
space
• Selectable SMBus addresses; multiple devices can easily
share an SMBus segment
