BCM53115MIPBG

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