    MIPI A-PHY Moves Ahead in IEEE Adoption Process

    Written by: Peter Lefkin, MIPI Managing Director
    1 March 2021

    MIPI A-PHY℠ v1.0 has now crossed an important milestone on its path toward adoption as an IEEE standard.

    On 10 February, the MIPI A-PHY adoption PAR (Project Authorization Request), known as "IEEE P2977™ Adoption of MIPI Alliance Specification for A-PHY Interface (A-PHY) Version 1.0," was approved by the IEEE Standards Association (IEEE SA) Standards Board, following a recommendation by the organization's New Standards Committee. The IEEE SA Corporate Advisory Group served as the project's sponsor.

    Latest Resources Cover MIPI A-PHY and Automotive SerDes Solutions

    Next-generation vehicles are rewriting the rulebooks when it comes to high-speed data interfaces. With the implementation of advanced driver assistance systems, high-definition in-vehicle infotainment and autonomous driving systems, the number of onboard cameras, sensors, displays and computing systems is increasing significantly—placing huge bandwidth demands on in-vehicle data interfaces.

    MIPI Protocol Adaptation Layers (PALs) — A Conversation with Raj Kumar Nagpal

    MIPI Alliance is rolling out a portfolio of Protocol Adaptation Layers (PALs) to support a range of important automotive sensor and display applications—advanced driver assistance systems (ADAS), autonomous driving systems (ADS) and in-vehicle infotainment (IVI), among others. The PALs enable upper-layer protocols such as MIPI Camera Serial Interface (CSI-2®) and Display Serial Interface (DSI-2SM) to be transported over MIPI A-PHYSM, the first industry-standard, long-reach serializer-deserializer (SerDes) physical layer interface.

    Raj Kumar Nagpal, interim chair of the MIPI PHY Working Group and lead of the MIPI A-PHY Subgroup, talks about how the PALs support A-PHY, as well as their contribution to the broader system of MIPI automotive connectivity solutions currently under development.

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

    Written by: Hezi Saar, MIPI Alliance Board Member
    12 January 2021

    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.
