12/8/4/2-Output PCI-Express Gen 1/2/3/4 and SRIS Clock

Generator

KEY FEATURES OR KEY POINTS

• 12/8/4/2-output low-power, push-pull HCSL

compatible PCI-Express Gen 1, Gen 2,

Gen 3, Gen 4 and SRIS-compliant outputs

The Si522xx is the industry's highest performance and lowest power PCI Express clock

generator family for 1.5–1.8 V PCIe Gen1/2/3/4 and SRIS applications. The Si52212,

Si52208, and Si52204 can source twelve, eight, and four 100 MHz PCIe differential

clock outputs, respectively, plus one 25 MHz LVCMOS reference clock output. The

Si52202 can source two 100 MHz PCIe clock outputs only. All differential clock outputs

are compliant to PCIe Gen1/2/3/4 common clock and separate reference clock architec-

tures specifications.

• Low jitter: 0.4 ps max

•

Individual hardware control pins and I C

controls for Output Enable, Spread

Spectrum Enable and Frequency Select

• Triangular spread spectrum for EMI

reduction, down spread 0.25% or 0.5%

The Si522xx features individual hardware control pins for enabling and disabling each

output, spread spectrum enable/disable for EMI reduction, and frequency select to se-

lect 133 MHz or 200 MHz differential output frequencies. These features can also be

controlled via I²C.

• Internal 100 Ω or 85 Ω line matching

• Adjustable output slew rate

• Power down (PWRDNb) function supports

Wake-on LAN (except Si52202)

The small footprint and low power consumption make this family of PCIe clock genera-

tors ideal for industrial and consumer applications.

• One non-spread, LVMCOS reference clock

output (except Si52202)

• Frequency Select to select 133 MHz or

200 MHz (except Si52202)

tion notes, and design tools, including the Silicon Labs PCIe Clock Jitter Tool for PCI-

Express compliance, please visit http://www.silabs.com/pcie-learningcenter.

• 25 MHz crystal input or clock input

•

I C support with readback capabilities

Applications

• Extended temperature: –40 to 85 °C

• Servers

• 1.5–1.8 V power supply, with separate

VDD and VDD_IO

• Storage

• Data Centers

• Small QFN packages

• PCIe Add-on Cards

• Network Interface Cards (NIC)

• Graphics Adapter Cards

• Multi-function Printers

• Digital Single-Lens Reflex (DSLR) Cameras

• Digital Still Cameras

• Digital Video Cameras

• Docking Stations

• Pb-free, RoHS-6 compliant
