BCM54210中文资料Single Port RGMII SGMII Gigabit Ethernet Transceiver数据手册Broadcom规格书

描述 Description

The Broadcom® BCM54210 is a fully integrated gigabit copper transceiver with support for Energy Efficient Ethernet (EEE), Synchronous Ethernet (SyncE), and IEEE 1588v2 standards. The PHY performs all of the physical layer functions for 10BASE-T, 100BASE-TX, 1000BASE-T, and on standard Category 5 unshielded twisted-pair (UTP) cable. The BCM54210 supports both the SGMII and RGMII industry standards. The BCM54210 is based on Broadcom’s proven digital-signal processor technology, combining digital adaptive equalizers, ADCs, phase-locked loops (PLL), 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 BCM54210 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, as well as 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.
