company blog about One-Stop Supply of In-Vehicle Ethernet Chips: Automotive PHY Transceivers/Switches/Controllers

With the rapid development of smart connected vehicles, in-vehicle Ethernet has become the core communication technology in modern automotive electrical and electronic architectures. Compared to traditional CAN/LIN buses, in-vehicle Ethernet offers significant advantages such as high bandwidth, low latency, and low wiring costs, and is widely used in key areas such as ADAS (Advanced Driver Assistance Systems), smart cockpits, vehicle-to-everything (V2X) communication, and domain controllers.

Types of Automotive Ethernet Chips

Automotive Ethernet chips are divided into three core categories based on function and architecture, covering all scenarios of in-vehicle high-speed communication:

1. Automotive Ethernet PHY Chips (Physical Layer Transceivers)

100BASE-T1 PHY: The mainstream low-speed solution for in-vehicle applications, using single-pair twisted-pair transmission, suitable for cameras, radar, and sensors

Representative Models: NXP TJA1100/TJA1101/TJA1102, Marvell 88Q2110, Broadcom BCM89810

1000BASE-T1 PHY: Gigabit high-speed solution, meeting the high-bandwidth demands of ADAS and autonomous driving

Representative Models: NXP TJA1120/TJA1121, Marvell 88Q2112, Realtek RTL9010AA

10BASE-T1S PHY: Automotive low-speed multi-node bus, suitable for domain controllers and body control

Representative Models: NXP TJA1410, Realtek RTL9010XY

2. Automotive Ethernet Switch Chips

Multi-port TSN Switch Chips: Support Time-Sensitive Networking (TSN), suitable for central gateways, domain controllers, and ADAS

Representative Models: NXP SJA1110, Marvell 88Q5050, Yutai Micro YT9908/YT9911

Integrated PHY Switch Chips: Single-chip integration of multi-port PHYs, simplifying in-vehicle gateway design

Representative Models: Marvell 88EA6321A0, Realtek RTL9047AA, Broadcom BCM89500

3. Integrated Ethernet Controllers (MAC+PHY)

Single-chip integration of MAC and PHY, providing a complete Ethernet interface suitable for ECUs and in-vehicle gateways

Representative Models: NXP TJA1104 (MACsec), Microchip LAN8742, Renesas R-IN Series
