SM802111

ClockWorks™ GbE Dual 125MHz

Ultra-Low Jitter, LVPECL

Frequency Synthesizer

General Description

The SM802111 is a member of the ClockWorks™ family of

devices from Micrel and provides an extremely low-noise

timing solution for Gigabit Ethernet clock signals. It is

based upon a unique patented RotaryWave

architecture

that provides very-low phase noise.

The device operates from a 3.3V or 2.5V power supply

and synthesizes two LVPECL output clocks at 125MHz.

The SM802111 accepts a 15MHz LVCMOS reference

clock.

Data sheets and support documentation can be found on

Micrel’s web site at:

www.micrel.com.

Features

•

Generates two LVPECL clock outputs at 125MHz

•

2.5V or 3.3V operating range

•

Typical phase jitter @ 125MHz

(1.875MHz to 20MHz): 85fs (typical) at 3.3V

•

Industrial temperature range

•

Green, RoHS, and PFOS compliant

•

Available in 24-pin 4mm

4mm QFN

Applications

•

Gigabit Ethernet
