Valens Collaborates with Leading Sensor Vendor to Evaluate A-PHY Integration in Next-Generation Products

Valens, the semiconductor company that is pushing the boundaries of connectivity, announced that it has started an evaluation with Sony Semiconductor Solutions Corporation (Sony) to develop and integrate MIPI A-PHY technology into next-generation image sensor products.

A-PHY is a long-reach serializer-deserializer (SerDes) physical layer interface for long-reach, ultra-high-speed automotive applications. It was released by the MIPI Alliance in September 2020 as a standard seeking to simplify the integration of cameras, sensors and displays in vehicles, while also incorporating functional safety and security. Valens will be the first company to market with A-PHY compliant chipsets, having recently completed a successful tapeout of its VA7000 chipset family.

“It’s highly important for Sony to integrate the cutting-edge technology into our image sensors, and A-PHY serializer integration will provide significant benefits for our customers,” said Kenji Onishi, General Manager, Automotive Business Department, Sony Semiconductor Solutions Corporation. “The MIPI ecosystem is growing quickly, and we’re happy to be early adopters of this automotive connectivity standard. Valens is in a leading position with A-PHY, which is why it is so important for us to start this collaboration. We believe future models will have even higher resolutions. In addition, our company is preparing to integrate several features into their next-generation sensors, including metadata output, higher framerate, and wider bit depth – all of which will require an ultra-high-speed, long-reach connectivity solution such as MIPI A-PHY. We will continue to support not only A-PHY but also D-PHY, proprietary interfaces, and open-standard interfaces.”

Integration of A-PHY into system components such as image sensors and SoCs will eliminate the need for proprietary bridge solutions meant to extend CSI-2 and DSI-2 data streams, which would simplify car architecture and lower total system cost. A-PHY offers data rates as high as 16 Gbps with a roadmap to 48 Gbps and beyond, with an unprecedented ultra-low packet error rate (PER) of 10^-19 and high noise immunity to electromagnetic interference.

“We’re happy to support Sony in bringing optimized MIPI A-PHY architecture to the automotive industry,” said Gideon Kedem, Valens SVP and Head of Automotive. “A-PHY is marching steadily towards widespread market adoption – we expect A-PHY to be the dominant connectivity solution on the road in cars around the world within a matter of years, and this evaluation marks yet another milestone for MIPI A-PHY to that end.”
