BCM53115 Brief BROADCOMS NEW 65 NM SMART SWITCH ENABLES MASS DEPLOYMENT OF GIGABIT ETHERNET FOR THE CONSUMER MARKET FEATURES SUMMARY OF BENEFITS Highly integrated, 65-nanometer (nm) process, non-blocking Industrys first 65 nm 5-port Gigabit Ethernet (GbE) switch 5-port 10/100/1000 switch silicon that integrates: in a single chip enables ubiquitous deployment of GbE to Five 10/100/1000 PHYs consumer electronic devices and home networking Two fully integrated, GMII/RGMII/MII interfaces Inband equipment. Management Ports (IMP) for glueless connection to a CPU or Flexible solution enables cost-optimized consumer system WLAN. designs that require scalable interfaces to address every facet Patented ease of use capabilities: of the consumer market segment. LoopDTech technology provides loop detection without Broadcom-patented features provide unique and easy to use running Spanning Tree Protocol (STP). solutions to network loop and cable problems. LoopDTech CableChecker enables advanced cable diagnostics based on automatically detects network debilitating loops, reducing the Broadcom Convergence Algorithm. system cost. CableChecker can be run at any time to detect Virtual Local-Area Network (VLAN) cable length and problems without interrupting live traffic IEEE 802.1Q-based VLAN with 4K entries and keep consumers connected. Port-based VLAN VLAN feature ensures proper Layer 2 isolation and security. VLAN double tagging (Q-in-Q): Supports addition and Double tagging enables carrier class devices. removal of one or two tags and VLAN translation. MAC-based VLAN provides wireless AP security support. MAC-based VLAN Integrated QoS technology supports all types of consumer Quality of Service (QoS) connections, including VoIP, video, audio, and data. Priority Four selectable QoS per port SP and WRR and any can be assigned each traffic type to ensure guaranteed combination of SP and WRR scheduling. delivery of time-sensitive packets and efficient use of network Port, MAC, IEEE 802.1P, and IPv4/IPv6 DSCP-based QoS bandwidth. Performance Performance enhanced architecture supports line-rate data 9 KB jumbo frame support wirespeed performance for all transfer to ensure consumer data (video, audio, pictures, and fame sizes. files) are sent at wirespeed. 4K MAC addresses with automatic learning and aging 64 multicast group support Increased network security that blocks unwanted access. 128 KB packet buffer Provides an easy way to troubleshoot security problems. Allows data packet inspection to be offloaded from a products Provides enhanced network security and resiliency to keep the Central Processing Unit (CPU), thereby freeing up CPU home network running efficiently. bandwidth to provide superior performance. Traffic control allows rate control, which identifies and Security prioritizes different data packet types within the switch while IEEE 802.1x support for secure user authentication. simultaneously assigning voice packets a higher priority for DoS prevention hardware. outbound communications, in addition to Layer 2 and TCAM-based ACLs: 256 policy rules, rule-based filtering, and Layer 3 multicast table support for IPTV. QoS class modification rule-based metering and accounting 128-byte deep packet header lookup, 28-byte matching. Traffic control and network resiliency Storm control and port-based ingress/egress rate control Spanning Tree support (Rapid Spanning Tree and Multiple Spanning Treesup to 16) IPv4 IGMP and IPv6 MLD snooping IEEE 802.3x programmable per port flow control and backpressure Port mirroring, LLDP, LACPOVERVIEW SerDes/SGMII or GMII/RGMII/MII GMII/RGMII/MII Misc GMAC (IMP) GMAC (IMP) I/Os L2 Switching Logic MMU with Integrated Field Processor Packet Buffer GMAC GMAC GMAC GMAC GMAC GPHY GPHY GPHY GPHY GPHY BCM53115M Block Diagram The BCM53115 architecture is the optimal solution for consumer to drive GbE into the unmanaged and Smart switch, WLAN router, and switching needs with its support for high-performance line-rate CPE/Gateway markets with its comprehensive Layer 2 feature set, capabilities and ability to identify and prioritize different data packet support for both DSL/cable modem and WLAN connectivity, and an types within the switch while simultaneously assigning voice packets a industry-leading 5 Gb of switching capacityall on a single chip. higher priority for outbound communications.
