Global automakers and other automotive supply chain manufacturers are increasingly joining the expanding MIPI A-PHY® ecosystem to collaboratively drive product designs aimed at high-speed image sensor and display connections.
These companies fully recognize the strong adaptability of the specification in the long-term development roadmap, as well as its capability to meet the bandwidth and performance requirements of next-generation Advanced Driver Assistance Systems (ADAS) and Autonomous Driving Systems (ADS).

These latest developments, along with previous announcements from MIPI and the industry regarding the adoption of A-PHY by automakers and automotive suppliers, collectively mark a key milestone for MIPI A-PHY in the automotive industry, highlighting the industry cohesion of this open standard in the field of high-speed connectivity.
The Latest Version Supports Distributed and Emerging Architectures
The enhancements in MIPI A-PHY v2.0 are designed to meet the higher bandwidth demands of next-generation automotive distributed and other emerging architectures, making it more attractive within the automotive ecosystem. This version increases the maximum available data rate for single-channel downlink from 16 Gbps to 32 Gbps, while the new uplink also achieves an 8-fold rate increase, supporting up to 1.6 Gbps.
It is worth mentioning that A-PHY v2.0 maintains the upper-layer protocol unchanged, ensuring a smooth migration from older versions and simplifying the implementation process. The v2.0 version is fully interoperable with A-PHY v1.1 and v1.0, allowing devices from all three versions to coexist on the same network.
The A-PHY specification is also the foundation of MIPI’s Automotive Serial Deserializer Solutions (MASS), which provides end-to-end connectivity for cameras, sensors, and displays, with built-in functional safety, data security, and protection mechanisms.
A-PHY Intellectual Property Licensing Structure
MIPI’s intellectual property terms are very friendly to implementers, further promoting the application and implementation of A-PHY. In line with all MIPI specifications, MIPI members grant each other royalty-free patent licenses for the implementation of their respective MIPI specifications; no additional necessary patent licenses are required.
In addition to A-PHY, MIPI members can also utilize other specifications to support ADS/ADAS applications, including MIPI CSI-2® for cameras, various A-PHY protocol adaptation layer specifications, MIPI Camera Security Framework for protecting camera data streams, and MIPI DSI-2™ for displays, among others.
