BCM89890 | Multigigabit Automotive Ethernet PHY with MACsec. LS1046 Dual 10G XFI PHY MDIO problem - NXP Community

interfaces for seamless connection to host SoCs or switches. Timing & Sync: Includes PHY timestamping for IEEE 1588 / 802.1AS , essential for time-sensitive networking (TSN). Power & Reliability:

Vehicles are notoriously noisy electrical environments, plagued by interference from alternators, electric motors, and high-voltage wiring. The BCM89890 uses custom echo cancellation, digital signal processing (DSP) noise filters, and ultra-low transmission jitter architectures. This guarantees that even at peak 10 Gbps speeds, the transceiver meets stringent automotive EMI/EMC compliance requirements without requiring heavy or expensive shielding. 3. Time-Sensitive Networking (TSN)

The original 100BASE-T1 and 1000BASE-T1 standards (IEEE 802.3bw and 802.3bp) quickly became foundational for many applications, but the bandwidth demands of next-generation automotive systems soon outpaced them. The introduction of high-resolution 4K cameras, 4D imaging radar, and high-definition infotainment for rear-seat passengers necessitated a quantum leap in data rate.

Make sure you follow Broadcom’s layout guide for the magnetics (or use an integrated RJ45 with magnetics for bench testing). The BCM89890 is forgiving, but proper differential pair routing on the MDI side saves you a week of EMI debugging.

: Extensively stress-tested to meet the rigorous components-level reliability mandates set by the Automotive Electronics Council.

To use the BCM89890 in a design, you'll need to consider the following:

Fully compliant with the IEEE 802.3ch standard for multigigabit automotive Ethernet.

For years, cars had struggled with a messy web of heavy, expensive cables that could barely keep up with the data demands of modern technology. Enter the Broadcom BCM89890

If you tell me which you're most interested in (like autonomous driving or high-def infotainment), I can provide more technical details on how the BCM89890 handles that particular task. BCM89890 | Multigigabit Automotive Ethernet PHY with MACsec
