Broadcom BCM89890 is a multigigabit automotive Ethernet Physical Layer (PHY) transceiver specifically designed for high-bandwidth, secure in-vehicle networking. It was notable for being the industry's first PHY to comply with the IEEE 802.3ch standard for automotive multigigabit Ethernet. Key Technical Specifications Core Features & Capabilities : Acts as a
Modern vehicles are moving from a domain-centric topology (e.g., one module for chassis, one for body) to a (e.g., left-front zone, right-front zone). In a zonal ECU, the BCM89890 serves as the edge PHY, aggregating sensor data from legacy CAN/I2C buses and converting it to Ethernet for backhaul to the central compute. Multiple BCM89890 devices often surround a Broadcom or Marvell switch chip.
