9DBU0731
DATASHEET
Description
The 9DBU0731 is a member of IDT's 1.5V Ultra-Low-Power
(ULP) PCIe family. The device has 7 output enables for clock
management, and 3 selectable SMBus addresses.
Recommended Application
1.5V PCIe Gen1-2-3 Fan-out Buffer (FOB)
Output Features
• 7 – 1-167MHz Low-Power (LP) HCSL DIF pairs
Key Specifications
• DIF additive cycle-to-cycle jitter <5ps
• DIF output-to-output skew < 60ps
• DIF additive phase jitter is <300fs rms for PCIe Gen3
• DIF additive phase jitter <350s rms for SGMII

Features/Benefits
• LP-HCSL outputs; save 14 resistors compared to standard
HCSL outputs
• 36mW typical power consumption; eliminates thermal
concerns
• Outputs can optionally be supplied from any voltage
between 1.05 and 1.5V; maximum power savings
• Spread Spectrum (SS) compatible; allows SS for EMI
reduction
• OE# pins for each output; support DIF power management
• HCSL-compatible differential input; can be driven by
common clock sources
• SMBus-selectable features; optimize signal integrity to
application
• slew rate for each output
• differential output amplitude
• Device contains default configuration; SMBus interface not
required for device operation
• 3.3V tolerant SMBus interface works with legacy controllers
• Three selectable SMBus addresses; multiple devices can
easily share an SMBus segment
• Space saving 40-pin 5x5mm VFQFPN; minimal board
space

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 9DBU0731. These ratings, which are standard
values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other
conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the
recommended operating temperature range.
