SM802XXX

Flexible Ultra-Low Jitter Clock Synthesizer

Clockworks™ FLEX

General Description

Features

The SM802xxx series is a member of the ClockWorks™

family of devices from Micrel and provide an extremely

low-noise timing solution for applications such as (1-100)

Gigabit Ethernet, SONET, Wireless base station, Satellite

communication, Fibre Channel, SAS/SATA and PCI-e. It is

based upon a unique PLL architecture that provides less

than 250fs phase jitter.

• 115fs at 156.25MHz (1.875MHz to 20MHz)

• 245fs at 156.25MHz (12kHz to 20MHz)

• On chip power supply regulation for excellent board

level power supply noise immunity

• Generates up to 8 combinations of differential or 16

single-ended clock outputs.

− LVPECL, LVDS, HCSL, LVCMOS (SE or Diff)

• Selectable input:

The devices operate from a 2.5V or 3.3V power supply

and synthesize up to 8 different combinations (LVPECL,

LVDS, HCSL) of differential or 16 single ended output

clocks. The devices accept an external reference clock or

crystal input.

− Crystal: 11MHz to 30MHz

− Reference input: 11MHz to 80MHz

• No external crystal oscillator capacitors required

• 2.5V or 3.3V operating power supply

• Available in Industrial Temperature range

The SM802xxx series is fully programmable and a web

tool is available to configure a part for samples at:

http://clockworks.micrel.com/micrel/

• Available in Green, RoHS, and PFOS compliant QFN

Datasheets and support documentation are available on

Micrel’s web site at: www.micrel.com.
