Four 10/100/1000 transceivers (802.3ab compliant) Four MACs (802.x compliant) with support for 9 Kbyte Jumbo Frames Nonblocking four Gigabit Ethernet fully integrated switch fabric SPI Interface for easy setup and smart unmanaged operation • Classifies packets using four 802.1p QoS or DiffServ/TOS priority queues • • • • • • • • • • VLAN 4k 802.1Q or port-based supported • Provides the most cost effective Gigabit Ethernet connectivity to the desktop for all remote, branch, and home office needs. • 802.1Q tag VLAN, trunking, and 802.1p priority enables the switch to be designed into a wide variety of applications from unmanaged to smart switch. • Jumbo frame support allows the device to be connected to corporate server farms and networks while maintaining maximum TCP/IP performance. • CPUs are not required to initialize and run in cost-sensitive Supports up to 8k unicast MAC addresses unmanaged applications, providing true Plug and Play connectivity. Supports MAC-based port aggregation (trunking) Flow control: full-duplex (802.3x) and half-duplex options supported • Internal oscillator circuit simplifies design and reduces overall system cost. • On-chip HP auto-MDI/MDIX on all transceivers automatically detects Supports automatic address learning and aging and corrects for crossover cables and allows direct switch-to-switch connection. Internal oscillator circuit Low power 0.13 µm 1.2 V CMOS core: <3.5W Pd. • Lowest possible system cost through minimized number of Fanless operation supported • Higher system reliability and noise reduction due to elimination of components. Integrated voltage regulator for simplified power supply design component with lowest MTBF (the fan). 324-pin FBGA package (small form factor 19 mm x 19 mm) 4 Gigabit Ethernet Ports for SOHO and Subnetwork Applications Printer Cable/DSL/Wireless Router IP Phones OVERVIEW Copper Interface Port 0 Gigabit PHY Gigabit MAC Switch Controller Copper Interface Port 1 Gigabit PHY Gigabit MAC Quality of Service (QoS) Copper Interface Port 2 Gigabit PHY Gigabit MAC Copper Interface Port 3 Gigabit PHY Gigabit MAC Internal Regulators MII Management VLAN Register Space SPI Interface or EEPROM Interface Jumbo Frames Port Trunking Configuration Pins Memory Rate Control Address Management Port Mirroring The Broadcom BCM5384 device is a highly integrated solution. It combines all the functions of a high-speed switch system, including packet buffer, PHY transceivers, media access controllers, address management, and a nonblocking switch fabric into a single 0.13 µm CMOS device. It complies with IEEE 802.3, 802.3u, 802.3ab, and 802.3x specifications, including the MAC control, pause frame, and auto-negotiation subsections, providing compatibility with all industrystandard Ethernet, Fast Ethernet, and Gigabit Ethernet devices. This device contains four full-duplex 10/100/1000BASE-T transceivers, each of which performs all of the physical layer interface functions for 10BASE-T Ethernet on Category 3, 4, or 5 unshielded twisted-pair (UTP) cable and 100/1000BASE-T Fast/Gigabit Ethernet on Category 5 UTP cable. The media access controllers on the BCM5384 also support Jumbo Frames which are typically used for high-performance connections to servers because they offer a smaller percentage of overhead on the link for more efficiency. SPI or EEPROM interfaces provide easy programming of the on-chip 802.1p QoS and/or DiffServ/TOS. This allows switch traffic to be given different classes of priority or service-for example, voice traffic for IP phone applications, video traffic for multimedia applications, or data traffic for e-mail applications. Up to 4k virtual LANs (VLANs) can be set up via the SPI port for separation of different users or groups on the network. For multi-Gigabit per second connections, multiple ports of the BCM5384 can be grouped together to form logical links. These links feature automatic load balancing.
