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
