Abstract

Automotive applications continue to advance with new features such as 360-degree eye views and interior vehicle monitoring to check for driver awareness. To support these features multiple cameras must be installed around and within the vehicle, with each camera requiring additional hardware and cabling components. FPDLink devices can simplify automotive system designs by transmitting both video data and power over a single standard coaxial cable between the camera and serializer. This decreases weight, removes the need for separate power supplies, and minimizes cabling costs.

This application note outlines design requirements and guidelines for implementing an FPD-Link ADAS system based around a Power-over-Coax (PoC) network. The application note also provides several TI reviewed PoC networks for use with FPD-Link IV and III devices.
