MIPI Alliance improves autonomous driving, other automotive applications with new data interface specifications

The MIPI Alliance, an international organization that develops interface specifications for mobile and mobile-influenced industries, announced this week that it 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.

Technology and automotive companies are invited to join the many MIPI Alliance members already involved in these efforts.

Companies participating in the MIPI Automotive Working Group include Analog Devices, Analogix Semiconductor, BitifEye Digital Test Solutions GmbH, Cadence Design, Fraunhofer IIS, Intel, Keysight Technologies, L&T Technology Services, MediaTek, Microchip, Mixel, Mobileye, an Intel company, NXP Semiconductors, OmniVision Technologies, ON Semiconductor, Parade Technologies, Prodigy Technovations, Qualcomm, Robert Bosch GmbH, Samsung Electronics, Socionext Inc., Sony, STMicroelectronics, Synopsys, Tektronix, Teledyne LeCroy, Toshiba, University of New Hampshire InterOperability Lab, Valens Semiconductors and others.

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. Its 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 ideal for applications such as IoT and industrial.

“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 Alliance is uniquely positioned to bring its strong knowledge and expertise of developing low electromagnetic interference (EMI) and low power interfaces in mobile to new environments such as automotive and IoT,” said Joel Huloux, chairman of MIPI Alliance. “Mature MIPI interface specifications for camera, display, sensors and physical layers are deployed in billions of mobile devices and are already prevalent in mobile-influenced industries such as automotive today. As MIPI’s specifications are designed to work together as a complete ‘stack,’ the addition of the longer reach MIPI A-PHY will provide greater ease of integration, resulting in an even richer solution.”
