What will be the in-vehicle connectivity gold standard for ADAS?

The automotive market is very close to adopting the MIPI A-PHY standard for CSI-2 and the DSI-2 standard for connectivity.

Daniel Shwartzberg, director of automotive system solutions at Valens hopes that is will become the connectivity solution of choice. He believes it will offer the automotive industry a standardized SerDes solution for high bandwidth, ultra-low latency, including EMI-EMC robust data links for video.

He explains: “Until this point OEMs and automotive suppliers (Tier 1s) have had to use proprietary, single source solutions for extending video within the vehicle but the A-PHY standard will enable an ecosystem of vendors supplying multiple interoperable products into the market.”

The trouble is, according to Shwartzberg, the words ‘proprietary’ and ‘single source’ aren’t words that the automotive industry enjoys. However, he suggests that a standard offers choice. Yet, there could be a counter-argument that it can restrict innovation. Putting that aside, he describes A-PHY as “a standardized solution offering multi-gigabit link speeds for sensor and display connectivity – things like cameras, radars and LiDARS”.

A-PHY endorsements

Companies and organizations are endorsing A-PHY. They include automotive suppliers such as Aptiv and Denso; camera and sensor vendors such as Omnivision; Leopard Imaging and Sunny Optical, SoC (System on a Chip) vendors like Mobileye; System in Package (SiP) vendors such as LG-Innotek; connector vendors such as Sumitomo; and test equipment vendors like Keysight.
