[time-nuts] sine to square wave circuits - performance data?

The "LPRO User's Guide & Integration Guidelines" includes phase noise 
data for 4 different sine to square converters in Section 3.4.

I used a similar circuit, but to improve performance at 2.5 MHz and 5 
MHz, I used 1000 pf for the input capacitor.  As expected, performance 
improves with higher frequencies and input levels.
