The is the world’s first IEEE 802.3ch compliant multigigabit Automotive Ethernet physical layer (PHY) transceiver chip . Designed specifically to handle the immense data requirements of modern connected vehicles, this highly specialized chip supports data transfer speeds of 2.5 Gbps, 5 Gbps, and 10 Gbps (10G/5G/2.5GBASE-T1) over a single shielded twisted-pair (STP) cable. Produced by Broadcom Inc., the BCM89890 represents a massive technological leap forward from older 100 Mbps and 1 Gbps automotive standards. It enables the multi-gigabit backbones required for autonomous driving, advanced driver-assistance systems (ADAS), and centralized zonal E/E (electrical/electronic) vehicle architectures. Core Specifications & Key Features
Vehicles are notoriously harsh electromagnetic environments, filled with noise from high-voltage powertrains and wireless signals. The BCM89890 utilizes advanced and digital signal processing (DSP) to achieve strict compliance with automotive EMI/EMC standards over a 15-meter cable track. Primary Applications in Modern Vehicles
Historically, automotive networks relied on slower protocols like CAN or FlexRay. The introduction of the BCM89890 allows manufacturers to replace heavy, expensive cabling with a single, lightweight cable capable of 10Gbps speeds. This reduction in cable weight directly contributes to better fuel efficiency and longer range for electric vehicles (EVs).
