HDMI, line is apart from the line width, what is the impedance,
VGA, line is apart from the line width, what is the impedance,
Start (TYPE C), the line is apart from the line width, what is the impedance,
DVI, and line is apart from the line width, what is the impedance,
RJ45 line is apart from the line width, what is the impedance,
The great god, please give some advice,
CodePudding user response:
Specific lines to walk the line spacing and wide, is according to the characteristic impedance and the PCB layer is calculated, so the characteristic impedance is a factor in determining that person's line spacing and line width, in general, the differential signal characteristic impedance, is designed according to the 100 ohms single-ended signal characteristic impedance according to 50 ohm design, there are also some special signals, such as usb and pcie difference line generally adopts 90 ohms, VGA video signal using 75 ohms,
