Hi,
is a serial resistance of 22R in the USB data lines (D , D-) mandatory?
Because we have a design without the 22R resistors and it works well. Now we want to know if we have to do a redesign to implement the 22R resistors.
Solved! Go to Solution.

For mass production, i think you should add the series R. It's terminal matching resistors, the role is to eliminate the signal overshoot and get a better eye diagram.
