MIPI Alliance aims to advance autonomous driving

Other automotive applications also impacted by MIPI A-PHY v1.0 with new data interface specifications set at 12-24Gbps and beyond


With specific focus on supporting lidar, radar and camera integration for autonomous driving, the MIPI Alliance has mapped a course to address the automotive industry’s needs for high-speed data interface specifications.

With development of the MIPI A-PHY physical layer specification already underway to meet 12-24 gigabits per second (Gbps), requirements gathering has begun to support higher speeds including over 48 Gbps for display and other use cases. When complete, these specifications will serve a broad spectrum of the industry’s connectivity needs.

“Automakers around the globe are amid a tremendous wave of innovation related to autonomous driving, ADAS, new fuel-economy standards, vehicle electrification and connectivity, new business models, new forms of in-car infotainment and more,” said Ian Riches, executive director – Global Automotive Practice with Strategy Analytics. “With so many new applications to be supported in and across the vehicle, the auto industry is under pressure to more simply, efficiently and cost-effectively integrate disparate, high-speed data components from an increasingly large supply base.”

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.
