occheung 2d0a866274 2238: add spec on max voltage with term
Updates #35.
Same termination structure as bnc/sma-ttl card.
Technically the max allowable voltage with termination is a bit higher than 5V.
But it seems that it will still exceed the termination resistor rating limit at 5.5V.
The only method of acquiring V_ds & other parameters is by eye-balling the I-V curve of the MOSFET, which is not precise.
So the calculation assumes V_ds=0, just to be conservative.

Therefore, to emit a pulse that is less than 8ns, additional delay is needed such that the \texttt{ttl.on()} \& \texttt{ttl.off()} event are submitted at different coarse RTIO cycles.
