9DBV0631

DATASHEET

Description

Features/Benefits

The 9DBV0631 is a member of IDT's 1.8V Very-Low-Power

(VLP) PCIe family. The device has 6 output enables for clock

management and 3 selectable SMBus addresses.

• LP-HCSL outputs; save 12 resistors compared to standard

PCIe devices

• 55mW typical power consumption in PLL mode; minimal

power consumption

• Outputs can optionally be supplied from any voltage

Recommended Application

1.8V PCIe Gen1-2-3 Zero Delay/Fanout Buffer (ZDB/FOB)

between 1.05 and 1.8V; maximum power savings

• OE# pins; support DIF power management

• HCSL-compatible differential input; can be driven by

common clock sources

Output Features

• 6 - 1-200 MHz Low-Power (LP) HCSL DIF pairs

• Spread Spectrum tolerant; allows reduction of EMI

• Programmable Slew rate for each output; allows tuning for

various line lengths

Key Specifications

• DIF additive cycle-to-cycle jitter <5ps

• DIF output-to-output skew <60ps

• DIF additive phase jitter is <100fs rms for PCIe Gen3

• DIF additive phase jitter <300fs rms for SGMII

• Programmable output amplitude; allows tuning for various

application environments

• Pin/software selectable PLL bandwidth and PLL Bypass;

minimize phase jitter for each application

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

• Configuration can be accomplished with strapping pins;

SMBus interface not required for device control

• 3.3V tolerant SMBus interface works with legacy

controllers

• Space saving 40-pin 5x5mm MLF; minimal board space

• 3 selectable SMBus addresses; multiple devices can easily

share an SMBus segment
