6-Output 3.3V PCIe Clock

Generator

9FGL0641 / 9FGL0651

Datasheet

Description

The 9FGL0641 / 9FGL0651 devices are 3.3V members of IDT's

3.3V Full-Featured PCIe family. The devices have 6 output

enables for clock management and support 2 different spread

spectrum levels in addition to spread off. The 9FGL0641 /

9FGL0651 supports PCIe Gen1–4 Common Clocked architectures

(CC), PCIe Separate Reference no-Spread (SRnS) and Separate

Reference Independent Spread (SRIS) clocking architectures.

Features

▪

Direct connection to loads saves 24 resistors compared to

standard PCIe devices

▪

188mW typical power consumption at 3.3V

▪

DDIO

rail allows 30% power savings at optional 1.05V

▪

SMBus-selectable features allows optimization to customer

requirements:

Typical Applications

▪

Servers/High-Performance Computing/Accelerators

▪

Storage

▪

Embedded Systems/Industrial Control

Output Features

▪

Six 100MHz Low-Power HCSL (LP-HCSL) DIF pairs:

33Ω, 85Ω or 100Ω output impedance for each output

▪

Devices contain default configuration; SMBus not required

•

Control input polarity

Control input pull-up/pull-down

Slew rate for each output

Differential output amplitude

•

9FGL0641 default Zo = 100Ω

•

9FGL0651 default Zo = 85Ω

▪

One 3.3V LVCMOS REF output with Wake-On-LAN (WOL)

support

▪

See

AN-891

for easy AC-coupling to other logic families

Key Specifications

▪

PCIe Gen1–4 CC compliant; Gen2–3 SRIS compliant

DIF cycle-to-cycle jitter < 50ps

DIF output-to-output skew < 50ps

DIF 12kHz–20MHz phase jitter is < 2ps rms when SSC is off

REF phase jitter is < 150fs rms; SSC off

±100ppm frequency accuracy on all clocks

▪

Contact factory for customized versions

25MHz input frequency

OE# pins; support DIF power management

Pin-selectable SRnS, CC 0% and CC/SRIS -0.5% spread

SMBus-selectable CC/SRIS -0.25% spread

Clean switching between the CC/SRIS spread settings

DIF outputs blocked until PLL is locked; clean system start-up

2 selectable SMBus addresses

Space saving 5 × 5 mm 40-VFQFPN package
