BCM5396 16-GE PORT SWITCH WITH INTEGRATED SerDes FEATURES SUMMARY OF BENEFITS Eighth-generation switch on a chip Enables a new generation of lower-cost switches with Gigabit Ethernet connectivity and much smaller form factors. Integrates Uses field-proven industry-standard Gigabit Ethernet SerDes One GMII/RGMII/RvMII interface which lowers overall system interoperability and reliability Seventeen MACs (802.x compliant) with support for 9-KB risks. jumbo frames Sixteen SGMII/SerDes interfaces and 256-KB packet buffer Provides the most cost-effective Gigabit Ethernet connectivity memory to the desktop and control plane for all remote, branch, and Enterprise needs. Non-blocking 17-Gigabit Ethernet fully integrated switch fabric SPI Interface for easy setup and managed operation 802.1Q tag VLAN, trunking, and 802.1p priority enables the switch to be designed into a wide variety of applications from Classifies packets using four 802.1p QoS or DiffServ priority unmanaged to websmart to managed switch. queues Jumbo frame support allows the device to be connected to VLAN 4k 802.1Q or port-based support corporate server farms and networks while maintaining Supports up to 4k unicast MAC addresses maximum TCP/IP performance. Supports MAC-based port aggregation (trunking) CPUs are not required to initialize and run in cost-sensitive unmanaged applications, providing true plug-and-play Flow control connectivity. Full-duplex (802.3x) and half-duplex options support Suitable for fully managed applications due to support for Supports automatic address learning and aging Spanning Tree and 802.1x MAC security Support for Spanning Tree and Rapid Spanning Tree SGMII interfaces ensure superior EMI performance and lowest possible number of required board layers while Low power 0.13 m 1.2 V CMOS core: <2.5W Pd. enabling connections to industry-standard physical layer Supports 802.1x MAC Security devices (e.g., BCM5464R) Port-based rate control feature with 64kbps granularity Lowest possible system cost through minimized number of external components. 256-pin FBGA package (small form factor 17 mm x 17 mm) Higher system reliability and noise reduction due to elimination of component with lowest MTBF (the fan). 16-Gigabit Ethernet Ports for SOHO and Subnetwork Applications Uplink Copper or Fiber IP Phones Server Cable/DSL/Wireless Router PrinterOVERVIEW Serdes Interface Deserializer Gigabit MAC BCM5396 Port 0 Serializer Serdes Interface Deserializer Gigabit MAC Port 1 Serializer Serdes Interface Deserializer Gigabit MAC Port 2 Serializer Serdes Interface Deserializer Gigabit MAC Port 3 Serializer Serdes Interface Deserializer Quality of Service Gigabit MAC Port 4 Serializer (QoS) MDIO / MDC Serdes Interface Deserializer Gigabit MAC Interface Port 5 Serializer VLAN Serdes Interface Deserializer Configuration Register Gigabit MAC Port 6 Serializer Pins Space Serdes Interface Deserializer Gigabit MAC Jumbo Frames SPI Interface or Port 7 Serializer EEPROM Interface Serdes Interface Deserializer Gigabit MAC Port 8 Serializer Port Trunking Serdes Interface Deserializer Gigabit MAC Port 9 Serializer Serdes Interface Deserializer Gigabit MAC Memory Port 10 Serializer Rate Control Serdes Interface Deserializer Gigabit MAC Port 11 Serializer Serdes Interface Deserializer Port Mirroring Gigabit MAC Port 12 Serializer Address Management Serdes Interface Deserializer Gigabit MAC Port 13 Serializer Serdes Interface Deserializer Gigabit MAC Port 14 Serializer Serdes Interface Deserializer Gigabit MAC Port 15 Serializer GMII, MII, or Gigabit MAC Switch Controller RGMII Interface BCM5396 Block Diagram The Broadcom BCM5396 device is a highly integrated solution ideally typically used for high-performance connections to servers because they suited for standalone Gigabit Ethernet switches and Gigabit Ethernet offer a smaller percentage of overhead on the link for more efficiency. control plane and backplane applications. It combines all the functions of SPI or EEPROM interfaces provide easy programming of the on-chip a high-speed switch system, including packet buffer, SerDes, media 802.1p QoS and/or DiffServ. This allows switch traffic to be given access controllers, address management, and a nonblocking switch different classes of priority or service. For example, voice traffic for IP fabric into a single 0.13 m CMOS device. phone applications, video traffic for multimedia applications, or data The BCM5396 complies with IEEE 802.3, 802.3u, 802.3ab, and 802.3x traffic for e-mail applications. Up to 4k virtual LANs (VLANs) can be specifications, including the MAC control, pause frame, and auto- set up via the SPI port for separation of different users or groups on the negotiation subsections, providing compatibility with all industry- network. For multi-Gigabit per second connections, multiple ports of the standard Ethernet, Fast Ethernet, and Gigabit Ethernet devices. BCM5389 can be grouped together to form logical links. These links feature automatic load balancing. The integrated sixteen SerDes cores enable direct connections across backplanes with the lowest possible amount of traces. The device also The BCM5396 can also be used in fully managed applications where integrates seventeen IEEE compliant 10/100/1000 MACs. Sixteen of support for Spanning Tree and 802.1x MAC security are a requirement. these are internally connected to the SerDes cores offering alternatively In such applications, the CPU will be connected using the SPI interface true serial interfaces for backplane connections or fiber optic for register control and the ninth MII interface for protocol frames. transceivers or SGMII interfaces for connection to industry-standard Finally, the BCM5396 supports per-port rate control for applications like Gigabit Ethernet copper transceivers such as the Broadcom BCM5464R. MTU/MDU switches where individual ports need to be restricted in The seventeenth MAC features multiple MII interface modes (RvMII, speed to comply with the agreed and paid for service levels. RGMII, GMII) for connection to a variety of CPUs.The media access controllers on the BCM5396 also support jumbo frames which are Broadcom , the pulse logo, Connecting everything , and the Connecting everything logo are among the trademarks of Broadcom Corporation and/or its affiliates in the United States, certain other countries and/or the EU.
