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.
