Sony debuts image sensor with MIPI A-PHY link

According to Sony, the IMX828 CMOS image sensor is the industry’s first to integrate a MIPI A-PHY interface for connecting automotive cameras, sensors, and displays with their ECUs. The built-in serializer-deserializer physical layer removes the need for external serializer chips, enabling more compact, lower-power camera systems.

The IMX828 offers 8-Mpixel resolution (effective pixels) and a 150-dB high dynamic range. Its pixel structure achieves a high saturation level of 47 kcd/m², allowing accurate recognition of high-luminance objects such as red traffic signals and LED taillights.

A low-power parking-surveillance mode detects motion to help reduce theft and vandalism risk. Images are captured at low resolution and frame rate to keep power consumption under 100 mW. When motion is detected, the sensor alerts the ECU and switches to normal imaging mode.

Sony plans to obtain AEC-Q100 Grade 2 qualification before mass production begins. The IMX828 meets ISO 26262 requirements, with hardware metrics conforming to ASIL-B and the development process to ASIL-D. Sample shipments are expected to start in November 2025. A datasheet was not available at the time of this announcement.
