We have very little direct information, only what's here: http://wiki.nesdev.com/w/index.php/Clock_rate

And this thread started by me about PAL's vertical chroma subsampling: viewtopic.php?t=11018 — there's clearly something funny going on where the 2C07 explicitly depends on chroma merging to get the "correct" hues.
