Thank you for the Gerber Data.
Can you please provide us with the stack up used for this layout?? As Gerber data has the stack up but it does not show the different trace widths considered for different impedances like 50E,90E,100E etc.
Also, if possible can you please let us know what is the impedance considered for SPDIFIn signals in this EVM layout? It is 50E or 75E or no impedance controlled followed??
