Description
The 9DBU0541 is a member of IDT's 1.5V Ultra-Low-Power
(ULP) PCIe family. It has integrated terminations for direct
connection to 100 transmission lines. The device has 5
output enables for clock management, and 3 selectable
SMBus addresses.

Features/Benefits
• Integrated terminations; save 20 resistors compared to
standard HCSL outputs
• 35mW typical power consumption; eliminates thermal
concerns
• Spread Spectrum (SS) compatible; allows SS for EMI
reduction
• OE# pins; 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 control
• 3.3V tolerant SMBus interface works with legacy controllers
• Selectable SMBus addresses; multiple devices can easily
share an SMBus segment
• 5 × 5 mm 32-VFQFPN; minimal board space
