General Description

The SM802128 is a member of the ClockWorks

™ family of

devices from Micrel and provides an extremely low-noise

timing solution for 10GbE 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

eight

LVPECL

output

clocks

at

156.25MHz or 312.5MHz. The SM802128 accepts a 25

MHz crystal or LVCMOS reference clock.

Data sheet and support documentation can be found on

Micrel’s web site at: www.micrel.com.

Features

• Generates eight LVPECL clocks at 156.25MHz or

312.5MHz

• 2.5V or 3.3V operating range

• Typical phase jitter @ 156.25MHz

(1.875MHz to 20MHz): 110fs with crystal reference

• Industrial temperature range (–40°C to +85°C)

• Green, RoHS, and PFOS compliant

• Available in 44-pin 7mm × 7mm QFN package
