Can anyone please suggest me how to isolate Composite Video coming from one unit to another unit's Video processing subsystem. Is there any IC available for Isolation.
I'm not sure I understand what you are looking for. How are these 2 units connected? What are you needing to isolate? What formats of video are you transferring?
I want to isolate composite (NTSC/PAL) video at the input of video distribution board. As we had mounted CCTV camera at one unit and taking output from there to Video distribution board which further goes to monitor. On displays i am getting some distorted video. It might be due to ground looping or other noise. So to eliminate this i want to isolate the input video coming from CCTV to VDU board.
We don't have any chip for something like that that I'm aware of. It sounds like something that would be done with passives-- or maybe there is some issue with your video distribution board.
I know we have optical isolation products, but I don't know enough about them to say they would be suitable and that seems like overkill anyway.
I assume the camera is far away from the distribution board. Have you considered using differential video to go from the camera to the distribution?
