OCTAL 10/100BASE-TX ETHERNET BroadR-Reach™ TRANSCEIVER

The BCM54881 is a member of Broadcom’s BroadR-Reach family of copper PHY products. It includes eight complete 10/100BASE-TX and BroadR-Reach transceivers integrated on a single 65 nm CMOS chip. The BCM54881 includes eight S3MII serial media access controller (MAC) 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/FFTB in MTU/MDU and hotels). The extended reach will also broaden the range of cable installations and CAN be used for new IP services and applications such as Broadband access, voice over IP, Wireless access points, and surveillance cameras. In contrast to previous technologies that extended the range of Ethernet over twisted pair, Broadcom’s new approach enables every BroadR-Reach port to also support IEEE 802.3-compliant technologies such as 10BASE-T and 100BASE-TX. As a result, BroadR-Reach guarantees interoperability and connectivity to standard 10/100BASE-TX devices, over distances up to 100 meters, while extending 10/100 operations over one, two, or four pairs of UTP cable up to 1000m, depending on the quality of the cable and number of pairs used.
