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.
