Valens Semiconductor, in collaboration with Sony Semiconductor Solutions, has successfully completed the Electromagnetic Compatibility (EMC) testing of their innovative A-PHY link system. This system is designed to enhance the integration and functionality of automotive sensors, specifically targeting the advanced driver-assistance systems (ADAS). The testing marks a significant step toward the development of the automotive industry’s first integrated sensor that supports high-speed connectivity, promising to make ADAS applications more efficient and cost-effective.

Key Highlights:

  • Successful EMC Testing: The collaboration between Valens Semiconductor and Sony Semiconductor Solutions resulted in successful EMC testing, including various stringent tests such as Bulk Current Injection (BCI) and RF Ingress.
  • First Integrated Sensor: The new technology aims to introduce the first-ever automotive sensor with an integrated high-speed connectivity solution, potentially simplifying the design and reducing costs of ADAS systems.
  • Growing A-PHY Ecosystem: Since the introduction of MIPI A-PHY in 2020, the technology has seen widespread adoption and interest from automotive OEMs and Tier 1 suppliers.
  • Upcoming Developments: Valens and Sony are now working on an 8 Megapixel A-PHY camera module specifically designed for ADAS, further advancing their collaborative efforts.

The MIPI A-PHY standard, first released in 2020, is pivotal in the automotive sector for enabling high-speed connectivity within vehicles. It is particularly tailored to support sensor integration, making it an attractive option for automotive manufacturers. Currently, several automotive OEMs and Tier 1 suppliers are exploring the integration of VA7000 MIPI A-PHY-compliant chipsets into their next-generation systems.

During their collaboration, Valens and Sony completed rigorous Interoperability Testing (IOT) and EMC testing. These tests were conducted using a 15m/40ft cable aged to simulate a full vehicle lifecycle, ensuring the system’s robustness and reliability in real-world automotive settings. This is crucial for maintaining the safety and effectiveness of electronic systems in vehicles equipped with ADAS and autonomous driving capabilities.

Kenji Onishi, from Sony, highlighted the progress, stating, “We are rapidly moving towards bringing to market the first-ever sensor with integrated high-speed connectivity, and these IOT and EMC tests are testament to the maturity of the A-PHY standard and our camera solution.”

Eyran Lida of Valens Semiconductor added, “The EMC testing proves, once again, the superior performance of A-PHY technology and the ability to build a truly interoperable ecosystem.”

MIPI Alliance chair, Sanjiv Desai, also commented on the successful collaboration: “This collaboration demonstrates both these goals, and we commend Valens and Sony for achieving this milestone. We’re pleased to see the continued growth and development of the A-PHY ecosystem.”

As the industry continues to evolve, Valens Semiconductor remains at the forefront, driving advancements in connectivity solutions that enable significant enhancements in digital automotive technology.
