BCM54180中文资料Octal SGMII Copper Gigabit Ethernet Transceiver数据手册Broadcom规格书

描述 Description

The Broadcom® BCM54180 is a fully integrated octal gigabit transceiver. The PHY performs all of the physical layer functions on standard Category 5 UTP cable, for 10BASE-T, 100BASE-TX, and 1000BASE-T. The BCM54180 is designed to support SGMII industry standards. The BCM54180 is based on the proven digital-signal processor technology from Broadcom, combining digital adaptive equalizers, ADCs, phase-locked loops, line drivers, encoders, decoders, echo cancelers, crosstalk cancelers, and all other required support circuitry integrated into a single, monolithic CMOS chip.Designed for reliable operation over worst-case Category 5 cable plants, the BCM54180 automatically negotiates with any transceiver on the opposite end of the wire to agree on an operating speed. The PHY can also evaluate the condition of the twisted-pair wiring to ensure that the wiring can support operation at Gigabit speeds, and detect and correct most common wiring problems. The device continually monitors both the wiring and the opposing transceiver and alerts the system if it detects potential problems with reliable operation.
