    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.
