PHY 8-CH 1000Mbps 10/100/1000BASE-T Transceiver

The BCM54880 is a member of the Broadcom GbE BroadR-Reach family of copper PHY products. It includes eight complete 10/100/1000 BASE-T and BroadR-Reach transceivers integrated on a single 65 nm CMOS chip. The BCM54880 includes eight SGMII serial media access controller interfaces and eight copper ports, whereby each copper port supports one, two, or four twisted-pair line connections. BroadR-Reach technology supports both 100-meter traditional Ethernet services and other applications that require longer than 100-meter reach or operation over a single twisted wire pair (such as FTTC/FTTB in MTU/ MDU as well as hotels). The extended reach also broadens the range of cable installations and can be used for new IP services and applications such as broadband access, voice over IP (VoIP), wireless access points, and surveillance cameras.Building on technologies that extend the range of Ethernet over twisted pair, Broadcom technology enables every BroadR-Reach port to also support IEEE 802.3-compliant technologies such as 10BASE-T, 100BASE-TX, and 1000BASE-T. As a result, BroadR-Reach guarantees interoperability and connectivity to standard 10/100/1000BASE-T devices over distances up to 100 meters while extending 10/100 operations over one, two, or four pairs of UTP cable for a distance of more than 1000m, depending on the quality of the cable and number of pairs used. Additionally, BroadR-Reach technology works in Power over Ethernet (PoE)-enabled platforms, providing a new generation of IP services and applications such as security camera surveillance.BroadR-Reach technology addresses key issues that affect deployment of IP services in today’s enterprise. For example, since many traditional digital PBX phone systems use twisted-pair cables that do not support standard IEEE 802.3 Ethernet PHY technology, BroadR-Reach is a good solution for migrating to IP-based telephony systems by leveraging the current infrastructure..
