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.

 

3 is difficult due to the multi ghz rate of the lines,
usb 2

advanced photronics just about have USB3 locked up

ebay et all have multiple "boxes" that claim unsb 3 speed, for around the USD 3 price

 

Amazon list a box for £379!!!
iFi Nano iGalvanic3.0 USB 3.0 Galvanic Isolator and Low Noise Power Hub

But a self-build would be non-trivial I suspect....

 

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.
