How do you calculate the PCB signals too be 50 Ohms? I have found http://www.saturnpcb.com/pcb_too...
It's a tool for making calculations, But w0067814 recommend that I should ask my PCB vendor to tell me the track widths and spaces,https://www.avrfreaks.net/index.p...
I want to know if I can trust this toolkit on calculations? I want to have a 10 layer PCB stack like this
So If I want to have 50 ohm tracks on layer one I should reference that to layer 3? is this a good layer stack up? and to have a 50 Ohm signal on layer 10 I should reference it to layer 8?
Do you have some track widths and spaces between tracks so I can compare them with this toolkit?
Can I reference my signals to GND, 3.3V and 1.2V planes for impedance calculations?
