In the high-stakes world of automotive engineering, a new hero was born: the BCM89890. This wasn't just any silicon chip; it was the world’s first IEEE 802.3ch compliant multigigabit Ethernet transceiver, a marvel of modern connectivity designed to be the central nervous system of the next generation of vehicles.

If you’ve been following the shift toward software-defined vehicles (SDVs) and zonal architectures, you’ve likely heard the buzz about Automotive Ethernet. But talk is cheap—literally, copper is cheap, and that’s exactly where the Broadcom BCM89890 shines. In the high-stakes world of automotive engineering, a

The Short Version: What is the BCM89890?

The BCM89890 is a 100BASE-T1 Ethernet PHY. In plain English: If you’ve been following the shift toward software-defined

• Camera Modules: Surround-view and driver-monitoring cameras use 100BASE-T1 to send raw or compressed video to the ADAS domain controller. The BCM89890’s low EMI prevents interference with sensitive RF components (e.g., GPS, 5G antennas).
• Radar/LiDAR: Corner radar modules use Ethernet to stream point cloud data. The BCM89890’s up to 40 meters of range allows sensors to be placed at the extreme corners of a large SUV.

Where You’ll Find It

• ADAS Cameras: The 100 Mbps is perfect for 1-2 MP cameras at 30-60 fps.
• Infotainment Head Units: Connects the central screen to the main backbone.
• Zonal Gateways: Links door modules, seat controls, and lighting to the central compute cluster.
• Industrial Robots & Cranes: Yes, it’s an automotive part, but the ruggedness makes it popular in factory automation, too.
