Hello,

 

Planning on designing with ADV7842 connected to an ADV8003.   In creating the schematic for this, I have referenced the Datasheet; the ADV7842 Eval Schematic; and ADV8003 Eval Schematic and they are all showing something different for hooking up Test4, Test5, Test8.  I've listed the conflicts and referenced the pdfs that I used.   Which one is the correct? Thank you!
