Hi all,
I need to design Gigabit Ethernet switch board using 6-layer PCB stackup. It requires 50ohm single ended and 100ohm differential impedance matching. I would be very grateful if someone can suggest some suitable example of such stackup. I know that the best practice is to ask manufacturer to suggest, but I am in a bit specific situation that I should suggest stackup, and manufacturer will follow it (I am limited to certain manufacturer). The suggested stackup should have reasonable trace width and distance between tracks within a pair. I worked with stackups that suggest over 0.25mm trace width for 50/90 ohm impedance, but I think it is too wide geometry for this project.
There were several examples on welldone blog, but it is currently no displaying pictures (https://welldoneblog.fedevel.com/201...your-projects/).
Thank you in advance.
