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 remaining four ports feature a standard RGMII interface to allow connection to Broadcom's market-leading 10/100/1000 transceiver family in order to provide fiber or copper Gigabit Ethernet connections. The media access controllers on the BCM5388 also support Port Trunking Memory Rate Control Address Management Port Mirroring 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 BCM5388 can be grouped together to form logical links. These links feature automatic load balancing.
