General Description
The Broadcom BCM5670 switch fabric is the central component of the modular and highly scalable StrataXGS Gigabit Ethernet switch architecture. StrataXGS components can be applied in a wide variety of configurations, enabling system designers to strategically balance cost, port density, and performance in the products they build.

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
• 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

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
