NXP Releases Complete Automotive Ethernet Product Portfolio


High-bandwidth technology to accelerate development of autonomous driving and secure connected vehicles


With the rapid increase of connectivity and communication within automobiles today, NXP have released its new product portfolio for automotive Ethernet. Ethernet is expected to provide the network backbone for autonomous driving and connected vehicles, as it is capable of the high data bandwidth, communications speed, weight reduction, and cost efficiency that future connected cars require.

This will also pave the way for new, distributed networking architectures (video) in the future.

The adoption of Ethernet is quickly accelerating with the rise of secure connected cars and the subsequent high demands for data transport.

“Automakers plan to use in-vehicle Ethernet broadly to enable a variety of applications and functions,” said Thilo Koslowski, vice president and automotive practice leader at Gartner. “These include safety, driver information systems, advanced driver assistance systems (ADASs) and entertainment. By 2023, 162 million Ethernet nodes containing 242 million ports will be included in produced consumer vehicles, worldwide.”

Jens Hinrichsen, senior vice president Secure Car Access & Networking at NXP added: “NXP has been a main driver in bringing Ethernet to cars and a founding member of the OPEN Alliance standardizing organization. It is inspiring to see the first 'true' automotive Ethernet transceivers and switches coming to market - ready to meet the stringent automotive requirements for EMC, quality, reliability, and volume production. The Ethernet portfolio rounds off our leading in-vehicle networking offering and will open up a variety of new features for future connected cars.”

Technical Highlights
By developing technology purpose-built for automotive applications, NXP's Ethernet PHY TJA1100 supports automotive low power modes. When the engine is off, the systems sleep. Meanwhile, the Ethernet PHY stays partially powered, waking up the system only upon activity on the network. Contrary to conventional solutions, the NXP Ethernet PHY does not require additional components like voltage regulators to stay on while the engine is off, which greatly improves power consumption and battery lifetime.

Transceivers - TJA1100

  • Compliant to OPEN Alliance BroadR-Reach™ (OABR) standard (IEEE: 100BASE-T1)
  • Designed following an automotive development flow
  • Form factor: 6x6mm HVQFN package with minimal external component count
  • Supports low-power modes to save battery life
  • Automotive grade ESD and EMC

NXP has developed the Automotive Ethernet Switch SJA1105 in close cooperation with TTTech, a global leader in the field of robust networking and safety controls. The switch uses Deterministic Ethernet technology to guarantee message latency in applications such as autonomous driving, where deterministic communication is vital for reasons of operational efficiency or functional safety. Deterministic Ethernet supports the trend toward increasing bandwidth requirements of up to one gigabit, while ensuring high reliability in networked control systems and high availability in fail-operational applications. It comprises several standards including Ethernet (IEEE 802.3), Time-Triggered Ethernet (SAE AS6802) as well as Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN).

Digital Switch - SJA1105

  • 5 Port automotive Ethernet Switch supporting network speed up to one gigabit
  • Layer 2 Store and Forward Switch
  • MII / RMII / RGMII Interface
  • Port Mirroring and VLAN support (IEEE 802.1Q and IEEE 802.1P)
  • AVB and TSN support
  • Enables Deterministic Ethernet solutions
    • Compliant to SAE AS6802 TTEthernet fault-tolerant clock synchronization
    • Virtual Link
    • Scalable, flexible and cost optimized configuration based on single and dual Port PHYs
