w/Zo=100ohms
9DBV0641
DATASHEET
Description
The 9DBV0641 is a member of IDT's 1.8V Very-Low-Power
(VLP) PCIe family. It has integrated output terminations
providing Zo=100ohms for direct connection to 100ohm
transmission lines. The device has 6 output enables for clock
management and 3 selectable SMBus addresses.
Recommended Application
1.8V PCIe Gen1-2-3 Zero Delay/Fanout Buffer (ZDB/FOB)
Output Features
• 6 - 1-200 MHz Low-Power (LP) HCSL DIF pairs
w/Zo=100
Key Specifications
• DIF cycle-to-cycle jitter <50ps
• DIF output-to-output skew <50ps
• DIF phase jitter is PCIe Gen1-2-3 compliant
• DIF additive phase jitter <300fs rms for SGMII

Features/Benefits
• Direct connection to 100ohm transmission lines; saves 24
resistors compared to standard PCIe devices
• 55mW typical power consumption in PLL mode; minimal
power consumption
• Outputs can optionally be supplied from any voltage
between 1.05 and 1.8V; maximum power savings
• OE# pins; support DIF power management
• HCSL compatible differential input; can be driven by
common clock sources
• Spread Spectrum tolerant; allows reduction of EMI
• 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
• 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 40-pin 5x5mm VFQFPN; minimal board
space
• 3 selectable SMBus addresses; multiple devices can easily
share an SMBus segment
