I already started to develop a gateway with this wireless module, ref WizFi630, and it seems for me to not have great difficulty to adapt WizFi630-EVB circuitry to our needs. It happens that I’m with some doubts with the correct dimensiong of the parameters of the high-speed signal lines(ethernet signals), and I don’t want to make mess with PCB layout. In did that is the only part of the pcb projcet that I didn’t finish.
I kindly ask if it is possible to access the gerbers of this evaluation board, ref WizFi630-EVB, or the pcb project. I don’t want to copy the board, I just to want to confirm my doubts and my calculus about lines impedance(I assume it’s 50ohms), and differential impedance of the pair lines.
If it is not possible to access the gerbers or the PCB project I would like to ask if it is possible to know the following parameters of the lines in this pcb board.
- h (thickness of the FR4 dielectric)
- Er(electric permitivity of the dielectric)
- spacing between differential microstrip lines.
- spacing from gnd to microstrip lines
- width of the lines
- thickness of the copper laminate
