BCM5670 8-PORT, 160 Gbps SWITCH FABRIC
FEATURES
•
Eight 10-Gbps (HiGig™) switch fabric ports
•
Nonblocking, 160-Gbps wire speed, backplane/switch fabric
performance
•
Forwarding rate of 119 million packets/second
•
Eight Integrated high-speed XAUI interfaces
SUMMARY OF BENEFITS
•
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.
