EXT_LFx pin of ADV7344

There are some questions about EXT_LFx pin of ADV7344.


The datasheet says that 12nF, 150nF capacitor and 170ohm resistor should be connected to EXT_LFx pin.


The issue occurs that mechanical shock by external makes some abnormal picture.

So, they tried to reduce the capacitor value(12nF->1.2nF, 150nF->15nF), then the issue is fixed.


Can ADV7344 accept above reduced capacitor value?


Best regards.
