Hi all
If a signal layer has digital and analog signals and sandwiched b/w gnd planes, which gnd is reference plane for inr1? If inr1 has digital signals on right and analog signals on left whereas inr2 has reverse,analog signals on right and digital on left.GND1 has split plane (analog/digital) as per INR1 and GND 2 has split plane as per inr2.
GND1
INR1
GND2
INR2
or we should have same cut out present in GND1 and GND2 to provide refrence gnd to INR1 layer?
Thanks
