Yes, the eval board doesn't have those connections because it's not
for evaluting that (it's just for testing the sync conversions I
guess), but I do have 5 of the chips, so if I can dig up a breadboard,
I can make a test system out of it (which I need to do anyways).

But the fact is, companies like Intersil (no, I don't work for them)
are making chips like the ISL59885 to get sync signals from video
streams without having to add all those extra componets.   Why build a
circuit with 20 parts, when a chip will take care of most of it?


But I am still curious as to what this composite signal is coming
from?

take care
