There's a block diagram on page 2 and more detailed circuit schematics starting on page 9.

Go here:-

and copy files pll.txt and pll.zip

Unzip the zip file and run the exe PLL_BODY

The program runs in DOS, but, runs OK under windows XP (don't know about Vista).

I'm amazed that this program has not been updated to run in a windows environment because it is absolutely brilliant. Unfortunately large parts of it are sequential so you have to keep re-starting it and going all the way through again, but, the guy who wrote it for Phillips ( Rob Volgers ) obviously really understood the 4046.
