ADAS Sensor Interconnect Reference Design Board for Remote Camera and Radar Modules

TIDA-00271

Overview

The ADAS Sensor Interconnect Board is intended for applications where remote sensors like cameras, LIDAR or radar modules need to be connected to a central processing ECU. The board supports up to 3 coaxial and 1 LVDS twisted pair data inputs as well as 3 FMC cable and 1 board to board connector as data outputs to a processing ECU.  Camera or other sensor modules connected through the coax connector (SMB standard) are powered directly via the coaxial cable (power over coax) from the interconnect board. Because of an independent complete power solution for all ICs and power over coax on board, a single car battery or similar wide voltage supply can be directly connected to the power connector on the ADAS Sensor Interconnect Board. An on-board uC and LIN interface allow control and configuration of the Interconnect board as well as plug-and-play operation.

Features
  • 3 High Speed FPD-III serial inputs each supporting a camera with bidirectional control, power and video link on a single coax cable with up to 1.4Gbps
  • Supplies up to 3 remote camera modules via power over coax (5V or 8V selectable)
  • Additional FPD-III serial input supporting a remote radar module with bidirectional control and 3Gbps data using STP cable
  • Built in self test (BIST) of all 4 serial inputs
  • Module can be supplied with a single voltage or directly from the car battery
  • This circuit is tested and includes Design considerations
