Brief
SCALABLE 12-PORT GIGABIT ETHERNET MULTILAYER SWITCH
BCM5691 FEATURES
• 12 10/100/1000 Mbps Ethernet ports supporting both
copper and fiber connections
• Integrated high-performance SerDes
• Gigabit Ethernet SerDes per port
• 4-pins per port SGMII interface to Gigabit Ethernet PHYs
• 32 million packets/second (line rate) aggregate
switching capacity
• ^{Supports 8 classes of service (CoS) per port}
• ^{Port trunking and mirroring supported across stacked}
switches
• ^{Fully integrated data and address memory on-chip}
• ^{Advanced packet flow control:}
• Head-of-line blocking prevention
• Full-duplex flow control (802.3x compatible)
• ContentAwareTM network processing per port
• Line rate multifield packet classification
• Supports IEEE802.1p, ToS/DiffServ, rate limiting, policing,
priority tagging, and remapping
• ^{Support for jumbo Frames of up to 9 KB}
• ^{Advanced diagnostic features including IEEE 1149.1}
JTAG boundary scan and BIST functionality
• ^{Low-power, enhanced thermal 480-pin EBGA package}
SUMMARY OF BENEFITS
• System vendors can build scalable high-performance,
high port density Gigabit Ethernet LAN switches in
several form factors.
• Multiple classes of service (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.
• Broadcom switch API compatability enables software
reuse and faster time-to-market
• Small package and low power enables cost-effective
and high-performance system design
TARGET APPLICATIONS
• ^{Multi-layer switch in modular Gigabit Ethernet switches}
• ^{High-port-count stand-alone or stackable Gigabit Ethernet}
• ^switches
Chassis and in-server switch blade applications
