Hi, i wanted to ask how are the standard difference signal lines rules when drawing differential lines in PCB layout? (please help, i need this as soon as it can be)
More info please:
But you need to know required characteristic impedance required for the signals, number of layers (and thus dielectric thickness), track width, etc etc.

Hi, thanks for the reply, i need to know the distance between tracks, track width and max length of the lines (tracks) between D+ and D- of USB lines, and between UART Rx and Tx lines. What values are the appropriate for a good performance?.

Impedance calculator.
USB D+/D- 90ohm diff impedance, max skew between lines 1mm (6 layer stripline routed approx. 0.17/0.17/0.17)
UART lines ref data sheet, but generally don't have to length match Rx Tx only diff pairs
