Black Box 1-Port USB-to-USB Isolator, 4 kV

hi my name is Mark Cantrell I'm an applications engineer with the AI coupler group here at analog devices I'm here today to introduce a new solution to a problem that has limited the acceptance of the Universal Serial bus in the industrial and medical markets these types of applications have strict isolation requirements for electrical connections to patients or dangerous machines however there's also a lot of pressure to take advantage of low cost computer hardware in the PC world the USB bus is the bus of choice it's self configuring hot swappable and nearly universally available but it is not easy to isolate it combines differential signals single-ended signals as well as passive States and all of these signals are bi-directional you can isolate USB in one of two ways first if you have flexibility in your design you can pull the USB function out of the controller and isolate the seri
