5-PORT MANAGED 10/100BASE-T/TX SWITCH

The Broadcom® BCM5304M is a five-port 10/100BASE-T/TX integrated switch targeted at cost-sensitive Fast Ethernet managed switch systems, SOHO routers and VoIP Telephony Systems. The device contains four 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.
