I found that AD-FMCADC4-EBZ is obsolete. also I found in this post that Analog Devices does not have any plan to build it again. We used some of these boards and we need it again, so we have to build it with Analog Devices Manufacturing files.
I did it, but i have some problem with manufacturing files. e.g. in the impedance model files declare: L/W=7.6 and space=10.4 or L/W=10 and space=15mil for differential 100ohm on bottom layer. but as I checked in gerber files for 100ohm differential lines like "REF_A_P" , "REF_A_N" L/W=5 and Space is 5mil. so which one is true? why you didn't declare it in impedance model file? also in gerber files in fab1 wrote:
"characteristic impedance = 100 ohm diff +/-10%
artwork line width for
impedance controlled lines = L/S 0.006" / 0.006" @ L1, L3 and L10"
really I am confused please help me to build this board.
any help would be greatly appreciated,
