Planning is well underway for the MIPI Automotive Workshop, coming up on 17 November 2021. The half-day virtual event, designed to provide a comprehensive look at the latest MIPI automotive specifications and initiatives, will benefit automotive developers, system architects and engineering managers who are focused on the design, development, integration and test of next-generation automotive E/E architectures.
As announced earlier this week, development is now complete on the next version of the MIPI A-PHYSM SerDes interface, which will double the maximum available downlink data rate from 16 Gigabits per second (Gbps) to 32 Gbps to support evolving requirements of automotive displays and sensors (cameras, lidars and radars). The enhanced version, v1.1, also will double the data rate available for uplink control traffic and introduce options for implementing A-PHY’s lower speed gears over lower-cost legacy cables, providing additional flexibility for manufacturers to implement A-PHY.
Due for release in late 2021, v1.1 will be fully interoperable with A-PHY v1.0, and devices using both releases will be able to coexist on the same network.
To provide additional support to developers working with the MIPI A-PHY℠ v1.0 specification, the A-PHY Working Group has released an Application Note for MIPI A-PHY Specification v1.0: Profile 1 and Profile 2 (for MIPI members), providing key performance indicators to help implementers design solutions that conform to the automotive long-reach serializer-deserializer (SerDes) physical layer specification.
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.
