Acting as the high-speed backbone connecting zonal controllers to central computing nodes.

This device is specifically designed for the demanding, high-bandwidth environment of modern, connected, and autonomous vehicles (AVs). Key Features and Capabilities The

The BCM89890 operates on a single 3.3V supply, but it has internal PLLs that need clean power. Use a dedicated LDO or a pi-filter from the vehicle’s main 3.3V rail.

By utilizing a single pair of shielded twisted-pair (STP) cables to deliver 10Gbps, the
