Bcm89890 -

The BCM89890 is packed with cutting-edge technology designed to meet the rigorous standards of modern vehicles. 1. IEEE 802.3ch Compliance (10G/5G/2.5GBASE-T1)

Broadcom has integrated hardware security features (MACsec support) into this line, which is becoming increasingly important as cars become connected devices vulnerable to hacking. From a design perspective, it integrates the termination resistors, reducing the Bill of Materials (BOM) count for engineers designing the PCBs.

To communicate with central gateway processors, electronic control units (ECUs), and network switches, the BCM89890 features state-of-the-art interface support:

Because encryption is executed at the hardware layer, it guarantees zero-latency cryptographic overhead, ensuring that safety-critical packets reach their destination unaffected. 3. Time-Sensitive Networking (TSN) & Clock Sync

Power consumption is a primary design constraint. The BCM89890 includes: bcm89890

Routes incoming cloud data and vehicle-to-everything (V2X) communication smoothly throughout the internal network architecture. Ecosystem Integration

Traditional multi-gigabit IT networking relies on four pairs of copper wires. The BCM89890 breaks this barrier for the automotive world by delivering . This significantly reduces vehicle weight, simplifies harness packaging, and lowers production costs. 2. Enterprise-Grade Security (MACsec)

For any OEM or Tier-1 supplier building a zonal architecture that requires robust 1Gbps connectivity without breaking the bank on 10G hardware, the BCM89890 is a top-tier choice. It is reliable, secure, and built to survive the harsh reality under the hood.

The stands as a groundbreaking milestone in the automotive semiconductor industry as the world's first IEEE 802.3ch compliant multigigabit Automotive Ethernet physical layer (PHY) transceiver . Developed by Broadcom Inc., this highly specialized chip is specifically engineered to handle the massive data payloads generated by modern software-defined vehicles, Advanced Driver Assistance Systems (ADAS), next-generation infotainment, and autonomous driving architectures. The BCM89890 is packed with cutting-edge technology designed

, 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

With vehicles increasingly connected via telematics, cars are vulnerable to external cyber threats. The BCM89890 features built-in IEEE 802.1AE MACsec hardware acceleration. By handling 128/256-bit AES encryption directly at the line-rate on the PHY chip, it prevents: Man-in-the-middle attacks Packet sniffing and data breaches Malicious payload injections

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.

Supporting high-resolution displays and rear-seat entertainment systems. From a design perspective, it integrates the termination

At its heart, the BCM89890 is a single-pair Ethernet (OPEN Alliance BroadR-Reach) PHY operating at 100 Mbps. Unlike traditional 100BASE-TX, which requires two twisted pairs, 100BASE-T1 uses just one unshielded twisted pair (UTP). This reduces wiring harness weight by up to 30% compared to legacy CAN or FlexRay—a critical savings in EV range and manufacturing cost.

Acts as the backbone for domain controllers and automotive gateways.
