Bcm89890 — Exclusive

The foundational capability of the BCM89890 is its full compliance with the IEEE 802.3ch 10G/5G/2.5GBASE-T1 standard. This allows it to support data rates of 10 Gbps, 5 Gbps, and 2.5 Gbps, providing a scalable and future-proof backbone for intra-vehicle communication. It achieves these speeds through advanced multi-level signaling (PAM4) modulation, a technique derived from high-performance data center networking.

If you’re designing a zonal architecture, you have three choices: CAN-FD (slow), 1000BASE-T1 (fast but power-hungry), or 100BASE-T1.

The versatility of the Broadcom BCM89890 makes it suitable for various high-end automotive applications:

, recognized as the world's first IEEE 802.3ch compliant multi-gigabit automotive Ethernet device. It is designed to handle high-bandwidth data demands for modern vehicles, including advanced driver-assistance systems (ADAS) and infotainment. Core Specifications Standards Compliance : Fully compliant with the IEEE 802.3ch standard, supporting speeds of 2.5G, 5G, and 10G over a single shielded twisted-pair (STP) cable. : Integrates 802.1AE MACsec bcm89890

Supports high-speed XFI and PCIe interfaces, optimized for connecting to automotive switch ICs or host SoCs.

High-throughput links between cameras, radars, and central computing units.

In the race toward Software-Defined Vehicles (SDVs) and zonal electrical/electronic (E/E) architectures, the spotlight often lands on high-performance System-on-Chips (SoCs) like the Nvidia Thor or Qualcomm Snapdragon Ride. But a vehicle’s nervous system depends just as critically on the unsung heroes of physical layer connectivity. The is precisely that: a highly integrated, automotive-grade 100BASE-T1 Ethernet PHY transceiver designed to move data reliably where fiber-optic and gigabit links are overkill or impractical. The foundational capability of the BCM89890 is its

: Fully compliant with IEEE 802.3ch, supporting 2.5 Gbps, 5 Gbps, and 10 Gbps speeds ( 10G/5G/2.5GBASE-T1 ).

: Implements low-power modes to reduce standby power consumption, a critical requirement for automotive "always-on" features.

designed for next-generation vehicle architectures. It is notable as one of the first transceivers to comply with the IEEE 802.3ch standard If you’re designing a zonal architecture, you have

: Operates cryptographic engines at full hardware speed with zero latency penalty.
