Thanks for all that.

One can never have too many PLLs, and never too much info to make modifications...

I suggest looking at Parasit's PLL build docs for more inspiration. A lot of my mods come start out essentially mixing and matching features found in his various circuits.
Also, look at the classic Schumann PLL, which the Data Corrupter is largely lifted from
