Introduction

Product Overview

The FM2112 is a fully-integrated, single-chip 24-port 10G/2.5G/1G

Ethernet layer-2 switch chip that offers wire-speed performance,

extremely low-latency characteristics, and leading power efficiency.

With its robust layer-2 switching capabilities and the ubiquity of

Ethernet, the FM2112 fits comfortably in a number of existing and

emerging applications. And, with the unprecedented level of

integration, the FM2112 removes the cost, area, and power barrier for

rapid and far-reaching high-performance Ethernet deployment.

Applications

With unprecedented integration, performance, power efficiency, and

latency characteristics, the FM2112 can be used for a variety of

infrastructure and interconnect applications, some of which include:

• Blade computer and IP storage platform internal fabric

• Data center cluster interconnect (clustered computers and storage resources)

• Enterprise stackable switch (performance workgroups and workgroup aggregation)

• AdvancedTCA backplane fabric (star or mesh architecture)

• AdvancedTCA carrier card switch (interconnecting mezzanine cards)

• AdvancedTCA base fabric

• Proprietary system backplane fabric
