MIPI Automotive SerDes Solutions (MASS), a standard framework providing end-to-end connectivity solutions for automotive sensors (camera/lidar/radar) and displays, has reached another important milestone with the release of three new standardized Protocol Adaptation Layers (PALs) for MIPI CSI-2®, MIPI DSI-2SM and Video Electronics Standards Association (VESA) Embedded DisplayPort/DisplayPort (eDP/DP).
Automotive display requirements are evolving rapidly as trends in connectivity, automation, sharing and electrification demand that automakers incorporate a growing number of larger and higher-resolution displays inside their vehicles. The use of visually lossless image compression will be essential to meet the bandwidth demands of these in-vehicle automotive displays and to ensure display connectivity solutions meet the stringent safety, reliability, power, weight and electromagnetic compatibility requirements demanded by the automotive industry.
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.
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 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.
Recently MIPI Alliance announced it had signed a memorandum of understanding (MoU) with IEEE, the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity. Under the agreement, MIPI A-PHYSM v1.0 will be brought forward through the adoption process to become an IEEE standard. In this Q&A, Joel Huloux, chairman of MIPI Alliance, discusses the significance of this announcement and the importance of liaison relationships, and shares a look ahead at what’s to come for MIPI Alliance.
