The specification is undergoing member review, with official adoption expected within the next 90 days. A-PHY will provide a physical layer for data transfers spanning an entire vehicle. As the first standard of its kind, it will help the automotive industry accelerate the availability of advanced driver assistance systems (ADAS), autonomous driving systems (ADS) and other surround-sensor applications, including cameras and in-vehicle infotainment (IVI) displays.
MIPI A-PHY serves as the foundation of what will be an end-to-end system designed to simplify the integration of cameras, sensors and displays, while also incorporating functional safety and security. Higher-layer MIPI protocols, such as Camera Serial Interface (MIPI CSI-2) and Display Serial Interface (MIPI DSI-2), are already used to connect sensors and displays to domain ECUs and other onboard computers in many vehicles. They currently are transported over MIPI C-PHY or D-PHY shorter-reach physical layers and use "bridge" solutions to connect to proprietary long-reach PHYs. With the use of upcoming adaptation layers, these higher-layer protocols will run natively over A-PHY, eliminating the need for proprietary bridge ICs.
