OVERVIEW 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. FEATURES • Highest silicon integration level achieved for an 4-port, 10/100/1000 Ethernet switch device • Seventh-generation switch on a chip • Integrates: 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 • Supports up to 8k unicast MAC addresses • Supports MAC-based port aggregation (trunking) • Flow control: full-duplex (802.3x) and half-duplex options supported • Supports automatic address learning and aging • Internal oscillator circuit • Low power 0.13 µm 1.2 V CMOS core: <3.5W Pd. • Fanless operation supported • Integrated voltage regulator for simplified power supply design • 324-pin FBGA package (small form factor 19 mm x 19 mm)
