    A Deep Dive into MIPI A-PHY and its Benefits for Automotive

    Written by: Hezi Saar, MIPI Alliance Board Member

    MIPI interface protocols are widely used in automotive to connect cameras, sensors, displays and other components to automotive systems on chips (SoCs). In a previous blog post, I detailed the automotive applications of MIPI CSI-2® and MIPI DSI-2SM, MIPI’s camera and display protocols, which have been broadly implemented in the industry. In September, the Alliance released MIPI A-PHYSM v1.0, the first asymmetric industry-standard, long-reach serializer-deserializer (SerDes) physical layer interface. In this post, I'll take a deep dive into MIPI A-PHY and provide a look at its key features and how they benefit some common automotive applications.

    MIPI in the News: A-PHY in EE Times and RFFE in IEEE Future Networks

    Two of the most significant MIPI highlights of 2020 were the eagerly anticipated releases of MIPI RFFE v3.0SM in April and MIPI A-PHYSM v1.0 in September. With the rollout of 5G well underway, and the rapid advancements in ADAS, ADS and IVI automotive applications, these specifications have generated tremendous interest for their roles in enabling these profound transformations.

    To share more about what these new specifications bring to their respective ecosystems, both were recently highlighted in industry publications. Here’s a look:

    Advancing Automotive Interoperability, Choice and Economies of Scale via Collaboration with IEEE

    The MIPI A-PHYSM v1.0 specification, which has been available to MIPI Alliance members since September 2020, is now positioned for wider availability to the broader automotive ecosystem.

    As detailed in an October 13 press release, under terms of a memorandum of understanding (MOU) with IEEE, the A-PHY serializer-deserializer (SerDes) specification will be put forward for adoption as an IEEE standard, which will result in broader global availability and, ultimately greater interoperability, choice and economies of scale for the global automotive industry.

    MIPI to Present SerDes Solutions at Upcoming Automotive Conferences

    MIPI Alliance will be bringing technical details on the new MIPI A-PHY℠ and MIPI Automotive SerDes Solutions (MASS℠) to two automotive conferences in the coming weeks. The presentations, at the Automotive SerDes Conference and AutoSens Detroit Edition, will offer virtual audiences the opportunity to learn more about MIPI's long-reach asymmetric, serializer-deserializer (SerDes) physical layer interface and how it serves as the cornerstone for end-to-end automotive system solutions.

    MIPI A-PHY v1.0 SerDes Specification for Automotive Now Available

    Innovations in automotive safety, automation and connectivity, including advanced driver-assistance systems (ADAS), comprehensive in-vehicle infotainment (IVI) and autonomous driving systems, are transforming vehicle design. New models coming in the next few years will have more high-resolution cameras, more advanced radar and lidar sensors, and more high-definition displays. All this will depend on reliable high-performance connections between sensors and displays and onboard computers, with functional safety and security built in.

    MIPI A-PHY Featured in Autonomous Vehicle Technology

    Improvements to driver assistance and self-driving systems hinge on collecting and using more data about a car’s surroundings. However, most vehicle networks were not built to support advanced features such as lane-keeping systems and multiple dash displays. As the industry moves toward self-driving and highly automated vehicles, automakers need new interfaces that can support new vehicle connectivity needs.
