Automotive electronics getting networked by Ethernet to have a distributed networking architecture. There is also a new standard for this; BroadR-Reach by the OPEN Alliance industry group.
NXP Semiconductors N.V. announced its new product portfolio for automotive Ethernet based on BroadR-Reach. NXP is sampling Ethernet transceivers (TJA1100) and Ethernet switches (SJA1105). Volume production scheduled in fourth quarter 2015.
Ethernet is also seen as better connectivity for cars to support autonomous driving and connected vehicles, due to its higher bandwidth and also security related features support.
By 2023, 162 million Ethernet nodes containing 242 million ports will be included in produced consumer vehicles worldwide, the market research data by Gartner shared by NXP in its release.
NXP said it has shipped six billion CAN, LIN, and FlexRay transceivers to the global automotive industry and two million transceivers are supplied every day. NXP launched Ethernet transceivers to have a strong presence in Ethernet connectivity in cars.
TJA1100 supports automotive low power modes, the Ethernet PHY stays partially powered, waking up the system only upon activity on the network. NXP Ethernet PHY does not require additional components like voltage regulators to stay on while the engine is off.
NXP said it 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)." explains NXP.
