Or something similar, its a good help to illustrate the issues.

It's not that good as an oscillator, but you can do some nice tricks. 
Then again, look at the oscillators I compare to. For shorter delays, it 
can be free-running, but longer delays needs the better oscillator or 
even external clocking.

The trigger jitter (alignment error between internal 80 MHz and trigger 
pulse) has an analogue fast-forward over to the output analogue delays, 
which is neat, but for better performance the trigger should preferably 
be done in the 10 MHz clock provided externally.

Cheers,
Magnus
