    New MIPI App Note Describes Validation Model for A-PHY v1.0 Transceiver Solutions

    Update: MIPI A-PHY was adopted as an IEEE standard in June 2021 and is also available as IEEE 2977-2021.

    To provide additional support to developers working with the MIPI A-PHY℠ v1.0 specification, the A-PHY Working Group has released an Application Note for MIPI A-PHY Specification v1.0: Profile 1 and Profile 2 (for MIPI members), providing key performance indicators to help implementers design solutions that conform to the automotive long-reach serializer-deserializer (SerDes) physical layer specification.

    MIPI A-PHY Moves Ahead in IEEE Adoption Process

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

    Update: MIPI A-PHY was adopted as an IEEE standard in June 2021 and is also available as IEEE 2977-2021.

    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

    Update: MIPI A-PHY was adopted as an IEEE standard in June 2021 and is also available as IEEE 2977-2021.

    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

    Update: MIPI A-PHY was adopted as an IEEE standard in June 2021 and is also available as IEEE 2977-2021.

    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

    Update: MIPI A-PHY was adopted as an IEEE standard in June 2021 and is also available as IEEE 2977-2021.

    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.
