BCM5380MKFB

The BCM5380MKFB device is a highly integrated solution. BCM5380MKFB combines all of 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-m CMOS device.It complies with the IEEE 802.3, 802.3u, 802.3ab 802.3x specifications including the MAC control,pause frame,and autonegotiation subsections,providing compatibility with all industrystandard rthernet,and fast ethernet,and Gigabit Ethernet devices.

Features of the BCM5380MKFB are:(1)the highest level of silicon integration achieved for an eight+two-port,10/100/1000 Ethernet switch device;(2)sixth-generation switch on a chip;(3)cascadable to 24 Fast Ethernet +6 Gigabit Ethernet ports through a SerDes expansion port,24FE + 2GE nonblocking;(4)packet classification 802.1p QoS priority queues;(5)VLAN 4K 802.1Q or port-based supported;(6)BCM5380MKFB has reverse MII,MII,or 7-wire interface supports an additional 100BASEFX or 100BASE-TX connection or uplink;(7)supports up to 4,000 unicast MAC addresses;(8)flow control:full-duplex (802.3x) and half-duplex options supported.If you want to know more information such as the electrical characteristics about the BCM5380MKFB,please download the datasheet in www.seekic.com .
