Ethernet Switch 5-Port 10Mbps/100Mbps/1Gbps 128-Pin PQFP
Manufacturer Part #: BCM5325FKQMG
Alternate Part #: BCM5325FKQMG
The Broadcom BCM5325 device is a highly integrated solution. It 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 0.18µ CMOS device. It 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.This device 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.E2PROM interfaces provide easy programming of the 802.1p QoS queues. 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.
