USB galvanic isolation - Page 2

felis · 6th October 2009, 05:58 AM

Just found this thread. My name is Oleg, I am C@Home guy. If you have questions about isolator, please ask. About power supply - the one supplying peripheral side is a pretty good switcher, definitely better than PC 5V through 6 feet of thin wire :-). It really shouldn't matter for audio - if device is bus-powered it will condition the supply and if it's self-powered, then supply is used only for isolator's peripheral side anyway:-). However, it can be bypassed altogether if necesssary.

Hi Oleg,
You might recognise my name here - we're in email correspondence at the moment. I should have pointed you to this board as it is where I picked up your site address from. Anyway, good to see you found your way here - I presume you noted a rise in orders for this kit as others ordered from you?

Hal06, let us know how it performs!

Maurico, and others,

I received several questions about PC refusing to recognize USB device connected through isolator and write a short article about what happens and how to possibly fix it ->USB Isolator Most Frequently Asked Question « Circuits@Home

optical fiber provides best isolation performance
a pulse transformer which provides normal common mode rejection is another choice

How are you planning to pass DC signals through a transformer?
