To whom may it concern,
I'd like use USB Isolator IC(ADuM4160 of ADI) and Hub IC(1:4).
I found that ADuM4160's reference schematic does not include 1.5kohm pull-up resistor in both UD+ net and UD- net for Full-speed.
So I have question about that.
Does ADuM4160 have internal 1.5kohm pull-up resistor in UD+ and DD+ for operation as full-speed?
by control SPU and SPD?
