Bcm89890 Guide

The is a pioneering multigigabit automotive Ethernet transceiver designed to meet the extreme bandwidth and security demands of next-generation vehicles. As the industry's first IEEE 802.3ch compliant physical layer (PHY) device, it supports data rates of 2.5G, 5G, and 10G over a single pair of shielded twisted-pair (STP) cables, effectively bringing data center-level speeds to the automotive environment. Key Technical Specifications

AEC-Q100 qualified with operation ranges from -40°C to +105°C, designed to withstand the harsh electromagnetic interference (EMI) and noise typical in automotive cabling. Transforming Vehicle Architectures

Acting as the communication link for zone controllers in engine bays or door cavities, allowing for reduced wiring weight and cost. The Future of Connectivity BCM89890 | Multigigabit Automotive Ethernet PHY with MACsec bcm89890
