So what I should have asked (what I meant to ask) is does anyone
have any data on this part to determine how long the
delay is? I'm
thinking it would be neat to try to use this (or a number of these in
series) to create a delay line memory to experiment with.
Little lumped-constant delays I doubt could hold more than 1 - 3 bits,
with a big bag of support logic.
But, you could play with one with an o'scope. DL's require correct
termination impedance, often 50 ohms. You put a (say) 10nS pulse in one
end, and it appears, delayed by more-than-the-speed-of-light, at the
other end. If you don't get the terminating impedances correct the pulse
will reflect and mess it up (the pulse, that is).
