Customer looking at the ADV7343.  There's two loop filters for the pll's, but we don't talk about them anywhere.  The only thing I saw in the data sheet was the typical application circuit, which had the loop filters populated.  Is there any information on these?  Are the componant values listed in the schematic valid for all conditions?  Customer wants to do both SD (16x oversample) and HD (4x) oversample.
