BCM5670
System vendors can build high-performance, high-density
Gigabit Ethernet LAN switches in several form factors.
Support for multiple CoS and very low latency enables the
support of VoIP and other voice, video, and data applications.
Built-in high-speed XAUI interfaces with Broadcom-unique
SerDes technology eases and accelerates system design, while
reducing cost and conserving board space.
A 1152-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.
Broadcom switch API compatibility enables reuse of resources
and fast time-to-market.
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
