When PCB layout area is not enough, we often use 4mil GND trace to shielding RF clock trace with 4mil spacing. , R. K1 F$ [1 [* x O5 \6 T* cIs this way enough to avoid RF clock signal to couple other signal trace near the 4mil trace?; B' T) R- E. I' X
Thanks
u r proposed to refer to 3W rule. # F3 p( \1 l7 l; {7 K& rwhen clock trace is 5 mils, u will need 10 mils spacing.2 v( g% d5 t. V/ A# X
of course GND trace will help, but PTH through holes with proper interval will do it better. # i5 a T" B, |5 N6 l# ?) _ 6 p' H4 f! e! f- E) Y9 o3 ?google it for detailed information, please!
