BCM5671

System vendors can build high-performance, high-density

Gigabit Ethernet LAN switches in several form factors.

Support for multiple CoS and very low latency enable the

support of VoIP and other voice, video, and data applications.

Built-in high-speed serial interfaces with Broadcom-unique

SerDes technology eases and accelerates system design, while

reducing cost and conserving board space.

A 640 KB internal data buffer memory eliminates the need for

expensive external memory.

Drives up to 10m of low cost copper cables for stacking switch

applications.

Switch fabric in modular Gigabit Ethernet switches

Switch fabric in high-port-count stand-alone or stackable

Gigabit Ethernet switches

Switch fabric for chassis and in-server switch blade

applications
