Broadcom BCM5419X Quad and Octal Gigabit Ethernet Transceiver with MACsec
Product Brief
Overview
The Broadcom® BCM5419X is a fully integrated quad (BCM54194) and octal (BCM54190, BCM54192, and BCM54195) gigabit transceiver family with standard compliant IEEE 802.1AE MACsec functionality on all ports. These devices are intended to provide a link security solution for both future and predecessor switching silicon that exceeds the requirements of IEEE 802.1AE MACsec standards. The BCM5419X family supports both controlled MACsec-encrypted frames and uncontrolled frames.
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 other physical layer functions for 100BASE-FX, 1000BASE-X, and SGMII-Slave.
The BCM5419X 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 BCM5419X device family 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.
