Regular ContributorHello,
The wire lengths in your PCB are all the same right?
Is there resistors in every wire? Where do you have this resistor?

qwitzaHello,
the wire length is in my first post, and yes they have all very near the same length.
the ksz9031 and the cyclone v are on the top layer, the resistors are on the bottom layer. the resistors are placed near the ksz9031.
thanks for your work, and answer
