描述 Description

The Broadcom® BCM54811S 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 BCM54811S is designed to comply with the SGMII industry standard and to exceed IEEE specifications for noise cancellation and transmission jitter, provide consistent and reliable operation over the broadest range of existing cable plants. The BCM54811S is based on proven Broadcom digitalsignal processor technology, combining digital adaptive equalizers, ADCs, phase-locked loops, line drivers, encoders, decoders, echo cancelers, crosstalk cancelers, and all other required support circuitry. This is designed to be fully compliant with SGMII, RGMII, and MII interface specifications, allowing compatibility with industry-standard Ethernet MACs and switch controllers. Designed for reliable operation over worst-case Category 5 cable plants, the BCM54811S automatically negotiates with its link partner to determine the highest possible operating speed. The device detects and corrects most common wiring problems. BroadR-Reach® enables the BCM54811S to auto-negotiate and link up with 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 type, individual parametrics, and number of pairs used).
