Description

The 9DBU0841 is a member of IDT's 1.5V Ultra-Low-Power

(ULP) PCIe family. It has integrated output terminations

providing Zo=100 for direct connection to 100

transmission lines. The device has 8 output enables for clock

management and 3 selectable SMBus addresses.

Features/Benefits

• Direct connection to 100 transmission lines; saves 32

resistors compared to standard HCSL outputs

• 53mW typical power consumption in PLL mode; 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; 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

• Pin/SMBus selectable PLL bandwidth and PLL Bypass;

optimize PLL to application

• Outputs blocked until PLL is locked; clean system start-up

• Device contains default configuration; SMBus interface not

required for device control

• Three selectable SMBus addresses; multiple devices can

easily share an SMBus segment

• 3.3V tolerant SMBus interface works with legacy controllers

• Space saving 48-pin 6x6mm VFQFPN; minimal board

space
