Hello,

I currently need to connect two different devices (twisted pair clabe, more than 10 feet) with LVDS signals. I would like to know how a safe galvanic isolation can be implemented with higher data rates than the 150 Mbps shown in the AN-1117 of Analog Devices.

Has anybody experience in this field?

How do industrial cameras and devices connected with LVDS signals (eg. DVI screens) look like in terms of isolation?

Thank you very much for your time :)
 

If you are willing to ensure a high-enough transition
density and DC balance then a transformer can be
good enough. Maybe a capacitor-blocked transformer
just for the stuck-at-DC problem.

There's a bunch of people making isolators now and
I'd be surprised if nobody did better than 150MBPS.
That's pretty leisurely.
