MIPI A-PHY (originally released to members in September 2020) is the first standardized, asymmetric, long-reach serializer-deserializer (SerDes) physical layer specification targeted for advanced driver-assistance systems (ADAS), autonomous driving systems (ADS), in-vehicle infotainment (IVI) displays and other surround-sensor applications (e.g., cameras, lidar, radar).

A-PHY's primary mission is to transfer high-speed data between cameras and displays and their related ECUs.

A-PHY offers:

  • High reliability: Ultra-low packet error rate (PER) of less than 10-19 for unprecedented performance over the vehicle lifetime
  • High resiliency: Ultra-high immunity to EMI effects in demanding automotive conditions
  • Long reach: Up to 15 meters
  • High performance: Data rate as high as 16 Gbps with v1.0; up to 32 Gbps with support for Star Quad (STQ) cables in v1.1
