I am making a camera system with a processing unit and a camerahead that only contains the imager and some passives. I was looking into the DS90UB913Q/DS90UB914Q because you can put the data and communication (I2C) over 2 wires.
Is it also possible to transfer the power for the camera over the same 2 RX/TX wires between the serdes pair?
If so how can this be done? Is there some circuitry needed to connect the supply to the link?
Best regards
Hi Jelko,
Yes, the power transfer can be combined on the same wires of the serdes FPD-link III interface. Please refer to the following article for power over FPD-Link concept – http://eetimes.com/design/automotive-design/4230494/Combine-power-feed-and-data-link-via-cable-for-remote-peripherals
