The Broadcom BCM5388 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 industry-
standard 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
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.
