The MIPI Alliance, an international organization that develops interface specifications for mobile and mobile-influenced industries, today announced the availability of MIPI A-PHY v1.0, the first industry-standard, long-reach serializer-deserializer (SerDes) physical layer interface.
The new specification, available to MIPI members, provides an asymmetric data link in a point-to-point topology, providing high-speed unidirectional data, embedded bidirectional control data, and optional power delivery over a single cable.
In conjunction with the availability of A-PHY v1.0, the Alliance today introduced MIPI Automotive SerDes Solutions (MASS). MASS will provide automotive OEMs and their suppliers with end-to-end high-performance connectivity solutions for the growing number of cameras, sensors, and displays that enable automotive applications such as advanced driver-assistance systems (ADAS), connected in-vehicle infotainment (IVI), and, ultimately, fully autonomous vehicles.
These solutions, with unprecedented functional safety and security built in at the protocol level, will help automakers integrate new and emerging safety features such as low-latency backup cameras, lane-keeping, and sign-detection sensors and a 360-degree camera, lidar, and radar systems. MASS also will support multiple high-resolution instrumentation, control and entertainment displays.
As the physical layer cornerstone, A-PHY's primary mission is to transfer high-speed data between cameras and displays and their related domain ECUs. Through the development of additional supporting specifications, MASS will allow proven higher-layer protocols from MIPI (such as MIPI CSI-2 and DSI-2) and third parties to operate over physical links spanning an entire vehicle, eliminating the need for proprietary “bridges” and PHYs. For OEMs and system integrators this equates to simplified networks and reduced costs, weight and development time.
