I do have PCB trace impedance matched to USB cable differential impedance (~90R).
As far as I know, I should also match the USB driver/transceiver impedance to the same differential impedance.
The problem is that I'm not able to find specifications for the driver pins:
Please can anyone advice, have you found the impedance specs for the usb driver pins?
Or am I missing something obvious about USB impedance matcing?
Thanks for any advice!
