Automotive 2-MP camera module reference design with MIPI CSI-2 video interface, FPD-Link III and POC


Design files


This camera module reference design addresses the need for small cameras in automotive systems by combining a 2-megapixel imager with a 4-Gbps serializer. Additionally, it provides power supplies and voltage supervision for both devices in an ultra-small form factor. This design includes a high-speed serial interface to connect a remote automotive camera module to a display or machine vision processing system with a coaxial cable transmitting both data and power. The 4-Gbps FPD-Link III SerDes technology used in this reference design enables the transmission of uncompressed 2 -MP video data, bidirectional control signals, and power over coax (POC) using a single cable.

  • Space optimized design with discrete power supply that fits on a single PCB 20 x 20 mm
  • Power supply optimized for high efficiency and low noise
  • 2-Mpixel IMX390 image sensor from Sony®
  • Provides RAW video data over MIPI CSI-2 interface
  • Includes precision voltage monitoring on all rails
  • Enables high-resolution camera applications using 4-Gbps DS90UB953
  • Single Rosenberger Fakra coax connector for digital video, power, control and diagnostics
  • Includes design considerations and BOM analysis
  • External frame sync capability
