BCM5670 8-PORT, 160 Gbps SWITCH FABRIC
FEATURES
SUMMARY OF BENEFITS
• 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
• 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
• I²C interface
• Broadcom switch API compatibility
• Advanced 0.13 µm CMOS technology
• Small 600-pin EBGA package
• Low power: 10W
• 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.
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
