DATASHEET

4-OUTPUT VERY LOW POWER PCIE GEN 1-2-3-4 CLOCK GENERATOR

9FGV0431

Description

Features/Benefits

The 9FGV0431 is a 4-output very low-power clock

generator for PCIe Gen 1, 2, 3 and 4 applications. The

device has 4 output enables for clock management and

supports 2 different spread spectrum levels in addition to

spread off.

• 1.8V operation; reduced power consumption

• OE# pins; support DIF power management

• LP-HCSL differential clock outputs; reduced power and

board space

• Programmable Slew rate for each output; allows tuning

for various line lengths

Recommended Application

PCIe Gen1-4 clock generation for Riser Cards, Storage,

Networking, JBOD, Communications, Access Points

• Programmable output amplitude; allows tuning for

various application environments

• DIF outputs blocked until PLL is locked; clean system

start-up

Output Features

• 4 – 0.7V low-power HCSL-compatible (LP-HCSL) DIF

pairs

• Selectable 0%, -0.25% or -0.5% spread on DIF outputs;

reduces EMI

• External 25MHz crystal; supports tight ppm with 0 ppm

synthesis error

• 1 – 1.8V LVCMOS REF output w/Wake-On-Lan

Key Specifications

• DIF cycle-to-cycle jitter <50ps

• DIF output-to-output skew <50ps

• DIF phase jitter is PCIe Gen1-2-3-4 compliant

• REF phase jitter is < 1.5ps RMS

• 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 32-pin 5x5 mm MLF; minimal board space

• Selectable SMBus addresses; multiple devices can

easily share an SMBus segment
