Description

The 9DBU0531 is a member of IDT's 1.5V Ultra-Low-Power

(ULP) PCIe family. The device has 5 output enables for clock

management, and 3 selectable SMBus addresses.

Features/Benefits

• LP-HCSL outputs; save 10 resistors compared to standard

HCSL outputs

• 35mW typical power consumption; eliminates thermal

concerns

• 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

• Spread Spectrum tolerant; allows reduction of EMI

• 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

• 3 selectable SMBus addresses; multiple devices can easily

share an SMBus segment

• 5 × 5 mm 32-VFQFPN; minimal board space
