Hello,
I'm trying to setup a completely isolated system. Everywhere I read(outside of single ap note from Analog) various sources say that it is not possible to isolate USB 2.0 HS or any form of USB 3.0.
But I have seen at least 2 different USB 3.0 to SATA converters out in the wild. And last time I checked, SATA used LVDS as its signaling layer. And there are 3 chips from Analog alone that will isolate LVDS at 600Mbps.
So why would the following not work:
Via Tech VL713 -- USB 3 to SATA
Analog Devices ADN4651 -- LVDS isolator with a max data rate of 600Mbps
USB 3.0 cable --> USB 3.0 socket -> usb 3.0 --> VIA VL713
--> LVDS --> AD4651 --> LVDS -->
VIA VL713 --> usb 3.0 --> usb3.0 socket --> usb 3.0 cable
Yes, it is a little round about and limited to 600Mbps, which is still MUCH faster than the current USB limit of 12Mbps.
With some attention to detail and not doing anything stupid, I don't see any problems.
VL710/3/6 $3 - $5 -- AliExpress --

Should this work

, or am I digging a whole I can't get out of??
