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
