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.

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 1.05V 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
• 5 × 5 mm 40-VFQFPN package; minimal board space
