Hello, does anybody know e circuit for high speed USB isolation.
http://www.advancedphotonics.co.jp/en/USB-480Mbps-isolation.html
The link above is with module that works on high speed I am curious how its made.
The only idea I have is to use converter from USB to serial interface ( maybe FPGA ) and isolated it with some of this IC https://www.analog.com/media/en/technical-documentation/data-sheets/ADN4650-4651-4652.pdf
But it is expensive, so I wonder does anybody have an idea how to design circuit that makes the isolation for High Speed USB.

How many ways do you know how to do isolation? If the answer is less than three, then it is probably one of the ways you don't know.

They use a laser. It's the obvious way.
