The MIPI Alliance has announced a mapped a course to address the automotive industry’s needs for high-speed data interface specifications. The MIPI Alliance is an international organization that develops interface specifications for mobile and mobile-influenced industries.
The Alliance has initiated development of a physical layer (up to 15m) specification targeted for ADS, ADAS, and other surround sensor applications.Requirements gathering has begun for higher-speed versions to provide greater bandwidth (e.g., 48 Gbps and more) for in-vehicle infotainment displays and other peripherals
The Alliance for this is inviting automotive OEMs, technology companies and suppliers to join and participate in future requirements gathering and specification development. Some of the companies participating in the MIPI Automotive Working Group include Analog Devices, Keysight Technologies, Microchip Technology, Mobileye, an Intel Company, NXP Semiconductors, OmniVision Technologies, ON Semiconductor, Qualcomm, Robert Bosch, Samsung Electronics, Sony, STMicroelectronics, Valens Semiconductors etc.
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.
Some of the advantages of MIPI-A-PHY will be its asymmetric nature, 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.
Joel Huloux, chairman of MIPI Alliance commented “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. 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.”
