BCM5671 4-PORT, 80-Gbps SWITCH FABRIC
FEATURES
SUMMARY OF BENEFITS
• Four 10-Gbps (HiGig™) switch fabric ports
• Nonblocking, 80-Gbps wire speed backplane/switch fabric
performance
• Forwarding rate of 60 million packets/second
• 4 integrated high performance XAUI interfaces
• Eight programmable priority queues per port
• Port trunking and mirroring across multiple devices
• Hot-swap capable with AC coupling
• Supports redundancy on linecards for chassis based
applications
• Advanced diagnostic features including IEEE 1149.1 boundary
scan, JTAG and extensive BIST functionality
• Resilient link configuration through active multipath
forwarding
• PCI interface
• Broadcom switch API compatibility
• Advanced 0.13 µm CMOS technology
• Small 600-pin EBGA package
• Low power: 6W
• 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.
TARGET 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
