Physical layer specification (up to 15m) advancing autonomous driving and other automotive applications
MIPI Alliance has initiated development of a physical layer (up to 15m) specification targeted for ADS, ADAS and other surround sensor applications.
MIPI A-PHY v1.0 is expected to be available to developers in late 2019. The specification will optimize wiring, cost and weight requirements, as high-speed data, control data and optional power share the same physical wiring. The asymmetric nature of the MIPI A-PHY link, its point-to-point topology and its reuse of generations of mobile protocols promise overall lower complexity, power consumption and system costs for developers and automotive OEMs. It’s anticipated that the first vehicles using A-PHY components will be in production in 2024.
In addition to automotive uses, the configuration of the specification will be well suited for applications such as IoT and industrial.
The MIPI Automotive Working Group (AWG), which developed the requirements for MIPI A-PHY v1.0, has begun requirements gathering to support higher speeds (e.g., over 48 Gbps) for display and other use cases.
