4 O/P 1.5V PCIe Gen1-2-3 ZDB/FOB

9DBU0431

DATASHEET

Description

Features/Benefits

The 9DBU0431 is a member of IDT's 1.5V Ultra-Low-Power

(ULP) PCIe family. The device has 4 output enables for clock

management, and 3 selectable SMBus addresses.

• LP-HCSL outputs; save 8 resistors compared to standard

HCSL outputs

• 45mW typical power consumption in PLL mode; eliminates

thermal concerns

Recommended Application

1.5V PCIe Gen1-2-3 Zero-Delay/Fan-out Buffer (ZDB/FOB)

• 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

Output Features

• 4 – 1-167MHz Low-Power (LP) HCSL DIF pairs

• SMBus-selectable features; optimize signal integrity to

Key Specifications

• DIF cycle-to-cycle jitter <50ps

• DIF output-to-output skew <50ps

• DIF phase jitter is PCIe Gen1-2-3 compliant

application

• slew rate for each output

• differential output amplitude

• Pin/software selectable PLL bandwidth and PLL Bypass;

optimize PLL to application

• DIF bypass mode additive phase jitter is <300fs rms for

PCIe Gen3

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

• Device contains default configuration; SMBus interface not

required for device control

• DIF bypass mode additive phase jitter <350fs rms for

12k-20MHz

• 3.3V tolerant SMBus interface works with legacy controllers

• Three selectable SMBus addresses; multiple devices can

easily share an SMBus segment

• Space saving 32-pin 5x5mm VFQFPN; minimal board

space
