Hi
Does anybody know a solution for a galvanic isolated USB interface using an
infineon C165UTAH ?
Thank you

What for?
Isn't it simpler to isolate the part of the circuit that really needs to
be isolated? Who cares if the USB side itself isn't?

Maybe isolate only USB chip (like USBN.....) with 3 optron (RXD TXD CLK)
is more simply that USB?

If you're using a separate USB tranceiver (Philips makes them) then you can
isolate between that and the USB controller using a magnetic isolator (high
speed compared to opto) and bus-power the transceiver. This works for full
speed. For high speed, you'd need to isolate a much wider bus so the
isolation will be more expensive. I haven't tried that.
