I am currently working on a 4-layer PCB that uses a Cypress PSOC4200 with a USB Full Speed connection. However, I am completely overextended with calculating the impedance and the resulting requirements of the traces.
I am working on a printed circuit board with the following layers:
Layer 1: Top (USB Signals) Layer 2: GND Layer 3: VCC Layer 4: Bottom
I want to layout the D+ / D- Signal Lines in CADSOFT Eagle, however this program does not offer calculation. Can anyone point me in the right direction? I have seen the PCB Saturn Software, but I am not sure what to fill in. I am planning to order the PCB from this manufacturer:
