While the BCM89890 serves the present generation of vehicles, engineers should note its place in the roadmap. For higher bandwidth (cameras > 2MP, raw LiDAR), Broadcom offers the (BCM89891 and BCM89892) which support 1000BASE-T1 (Gigabit over single pair). However, for the vast majority of sensors and ECUs deployed today, the BCM89890 remains the "sweet spot" for performance per watt.

As the automotive industry accelerates toward zonal architectures, Ethernet-enabled ECUs are proliferating. The is not just a PHY; it is an enabler of the software-defined vehicle. It allows a single twisted-pair wire—light, cheap, and flexible—to carry the same data as a legacy four-pair cable.
Hi， On my customized board, i have a Broadcom BCM89890 10g phy connected to XFI. 9 and a Marvell AQR113C 10g phy connected to XFI. NXP Community
