DS90UB941AS-Q1: Multiple Serialized videos over single Cable

Hi Wladimir,

What are the interfaces you would like to connect to? CSI to CSI? DSI to LVDS? 

Power over STP is possible, the power is sent across the STP cable by a DC voltage on top of the FPD-Link high speed signal.

Hi Michael,

This is my system

My goal is to use a single cable, as thin as possible (including maybe custom connectors), and potentially send other low speed signals alongside.

Hi Michael,

Thanks for the reply. But if I understand correctly, coax is not the only option but also STP. So what if I go for a multipair STP one-cable assembly?. For instance, a LAN Cable should work, or not?

Yes, I also have read that all those signals can be encapsulated on the FDP.

Wladimir

Hi,

Yes you can use STP, but for each video signal you will need a STP cable, so that would be 4 STP cables. I do not know if LAN cables will work because most customers do not use LAN cables. You will need to check the signal properties of the cable to determine if LAN cables can work in your application.

Hi,

Thanks for your answer. That means that I should use multiple single-pair STP cables?. If I plan to to a single assembly with four video signals, I guess that will end up as a very thick cable. In your experience, what is the thinner cable I could get for a SerDes carrying one video signal.?

thanks

Hi,

The thinnest cable that you can get to carry a video signal is a single coax cable for each video.
