BCM5695
®
MULTILAYER 12-PORT GIGABIT ETHERNET STACKABLE SWITCH
FEATURES
SUMMARY OF BENEFITS
• 12 10/100/1000-Mbps Ethernet ports with copper or fibre
connectivity
• HiGig+™ stacking port that runs at 10-Gbps or 12-Gbps speeds
• Integrated high-performance SerDes with XAUI™ interface on
the HiGig+ port and an SGMII interface on the Gigabit Ethernet
(GbE) ports
• Scalable up to 128 BCM5695 devices in a single configuration
• All address tables and buffer memory fully integrated on-chip
• Support for port trunking and mirroring across stacked links
• Support for jumbo frames of up to 9 KB in size
• Advanced full-duplex end-to-end flow and congestion control with
head-of-line blocking prevention
• ContentAware™ packet filtering and classification per-port
• Wirespeed operation
• Support for 802.1p, TOS/DiffServ, policing, shaping, marking, and
remarking
• Rate control of broadcast, unknown multicast and unicast packets
• Eight queues per port
• Support for double 802.1q VLAN tagging and VLAN translation
• Hardware-based IP multicast routing and forwarding
• Support for replication
• Equal and weighted cost multipath routing for load balancing
• Advanced diagnostic features including JTAG boundary scan and
BIST functionality
• Low power consumption of 4.65W in a 480-pin PBGA package
• Pin-to-pin compatible with the BCM5690
• Enables modular, scalable, and high-performance GbE switch
designs using switch fabric
• Facilitates seamless integration of voice, video, and data traffic
through low-latency and advanced QoS
• Enables lower system design cost and board space utilization
through superior integration and compact form factor
• Offers quicker time-to-market and software reuse through
backward compatibility with Broadcom switch software API
TARGET APPLICATIONS
