The BCM5325E is the feature-enhanced and pin-compatible six-port
switch to the industry leader BCM5325M ROBOswitch™. This device
combines all the functions of a high-speed switch system, including
packet buffers, PHY transceivers, MACs, address management, and a
non-blocking switch fabric, into a single 0.18-µm CMOS device. The
BCM5325E complies with the IEEE 802.3, 802.3u, and 802.3x
specifications, including the MAC control PAUSE frame and auto-
negotiation subsections, providing compatibility with all industry-
standard Ethernet and Fast Ethernet devices.
The BCM5325E contains five full-duplex 10BASE-T/100BASE-TX
Fast Ethernet 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 100BASE-TX Fast Ethernet
on Category 5 UTP cable.
The BCM5325E comes in the three options of BCM5325E,
BCM5325F, and BCM5325U. The BCM5325E and BCM5325U are
pin-compatible to the industry five-port FE leader BCM5325M and
BCM5325, respectively. The BCM5325F includes the PHY-MUX
option where the fifth 10/100 PHY can be configured to connect to MAC
4, MAC 5 internally or external MAC via MII. This allows the flexible
use of the fifth PHY for special application, or to be used with an external
WAN MII interface, ideal for broadband and SOHO gateway/router
applications.
In addition to the robust 10/100 Ethernet DigiPHY, the five-port switch
in the BCM5325E includes rich feature sets such as four priority queues
supporting port, MAC, 802.1p, DiffServ-based Class of Service suitable
for voice over IP, video, and data traffic for multimedia applications.
In addition, BCM5325E supports other advance L2 managed features
including port-based and 802.1Q VLAN, 802.1x EAPOL protocol
filtering, IGMP snooping, and mirroring.
