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
Packet-based switch fabric in telco applications
