According to ADV7343 datasheet, the external  loop filter looks like Fig. 92 (p.73).


The questions are;

1.     What kinds of side-effect  would occurr if the 150nF capacitor value would be changed between -20% (120nF)~+80% (270nF?) in the worst  case?

2.     How much margin would be  permitted in this capacitor, from design point of view?

As for Q1, since it determines the  filter characteristics, I assume the noise or something would be appeared in the  picture in the worst case.
