Broadcom Quad Octal Gigabit Ethernet Transceiver Part #BCM54140B0KFBG | IC | DEX

Overview

The Broadcom BCM5418X is a fully integrated quad (BCM54140) and octal (BCM54180, BCM54182, and BCM54185) gigabit transceiver family. The PHY performs all of the physical layer functions on standard Category 5 UTP cable for 10BASE-T, 100BASE-TX, and 1000BASE-T. When in Fiber mode, the PHY performs all the physical layer functions for 100BASE-FX, 1000BASE-X, and SGMII-Slave (BCM54140/BCM54185 only).

The BCM5418X device family is based on 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 the other required support circuitry integrated into a single, monolithic CMOS chip.

Designed for reliable operation over worst-case Category 5 cable plants, a BCM5418X device 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.
