The last of the "easy" sheets: the video decoder.
- there are numerous unused inputs that are left floating.
Shouldn't we rather ground them ? E.g., Ain1-3 to AGND, and
HS_IN/VS_IN to DGND.
- should we connect SOG/SOY ? At 6400% magnification, the value
of the capacitor connecting it to Y/G looks like 1 nF. Also
the ADV7181D, where AD made a less determined effort at
obfuscating the example circuit, uses 1 nF.
I suppose the load capacitors for Y2 with 33 pF each are
sufficient for the 20 pF required, considering parasitic
