Product Brief BCM54811 BroadR-Reach Single-Port 10/100/1000Base-T Transceiver Overview The Broadcom BCM54811 is a triple-speed 10/100/1000BASE-T Gigabit Ethernet (GbE) transceiver integrated into a single monolithic CMOS chip. The device performs all of the physical layer (PHY) functions for 1000BASE-T, 100BASE-TX, and 10BASE-T on standard Category 5 UTP cable. The 10BASE-T Ethernet can also run on standard categories 3, 4, and 5 UTP. The BCM54811 is designed to exceed IEEE specifications for noise cancellation and transmission jitter, providing consistent and reliable operation over the broadest range of existing cable plants. The BCM54811 is based on proven Broadcom digital signal processor technology, combining digital adaptive equalizers, ADCs, phase locked loops, line drivers, encoders, decoders, echo cancelers, crosstalk cancelers, and all other required support circuitry. The BCM54811 is designed to be fully compliant Key Features with RGMII and MII interface specifications, allowing compatibility with Single-chip integrated triple-speed industry-standard Ethernet MACs and switch controllers. Designed for Ethernet transceiver. Support for reliable operation over worst-case Category 5 cable plants, the BCM54811 the following copper line interfaces: automatically negotiates with its link partner to determine the highest 1000BASE-T IEEE 802.3ab possible operating speed. The device detects and corrects most common wiring problems. The BCM54811 features CableChecker diagnostics, which 100BASE-TX IEEE 802.3u detect common cable problems including shorts, opens, and cable length. 10BASE-T IEEE 802.3 BroadR-Reach enables the BCM54811 to autonegotiate and link up with 10 Mb/s BroadR-Reach BroadR-Reach compliant link partners in extended cable reach applications of 300m or 500m at 10 Mb/s and 100 Mb/s modes (depending on cable 100 Mb/s BroadR-Reach type, individual parametrics, and number of pairs used).
