BCM5389 8-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 Nine MACs (802.x compliant) with support for 9-KB jumbo risks. frames Eight SGMII/SerDes interfaces and 128-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 9-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 integration of full MIB counters 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: <1.5W Pd. enabling connections to industry-standard physical layer Fanless operation support 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). 8-Gigabit Ethernet Ports for SOHO and Subnetwork Applications Uplink Copper or Fiber IP Phones Printer Server Cable/DSL/Wireless RouterOVERVIEW SerDes Interface Deserializer Gigabit MAC Port 0 Serializer BCM5389 MDIO/ MDC Interface Quality of Service SerDes Interface Deserializer Gigabit MAC (QoS) Port 1 Serializer Configuration Register Pins Space SerDes Interface Deserializer VLAN Gigabit MAC SPI Interface or Port 2 Serializer EEPROM Interface SerDes Interface Deserializer Jumbo Frames Gigabit MAC Port 3 Serializer SerDes Interface Deserializer Port Trunking Gigabit MAC Memory Port 4 Serializer SerDes Interface Deserializer Gigabit MAC Rate Control Port 5 Serializer Address Management SerDes Interface Deserializer Gigabit MAC Port Mirroring Port 6 Serializer SerDes Interface Deserializer Gigabit MAC Port 7 Serializer SwitchController GMII, MII, or Gigabit MAC RGMII Interface BCM5389 Block Diagram The Broadcom BCM5389 device is a highly integrated solution ideally connections to servers because they offer a smaller percentage of suited for standalone Gigabit Ethernet switches and Gigabit Ethernet 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 BCM5389 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 eight SerDes cores enable direct connections across backplanes with the lowest possible amount of traces. The device also The BCM5389 can also be used in fully managed applications where integrates nine IEEE compliant 10/100/1000 MACs. Eight of these are support for Spanning Tree and MIB counters is a requirement. In such internally connected to the SerDes cores offering alternatively true serial applications, the CPU will be connected using the SPI interface for interfaces for backplane connections or fiber optic transceivers or SGMII register control and the ninth MII interface for protocol frames. interfaces for connection to industry-standard Gigabit Ethernet copper Finally, the BCM5389 supports per-port rate control for applications like transceivers such as the Broadcom BCM5464R. The ninth MAC features MTU/MDU switches where individual ports need to be restricted in multiple MII interface modes (RvMII, RGMII, GMII) for connection to speed to comply with the agreed and paid for service levels. a variety of CPUs.The media access controllers on the BCM5389 also support jumbo frames which are typically used for high-performance 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.
