Moin,
The last couple of days, I have been looking into sine to square
wave converters. There are a few proposed circuits[1-4] and there
is of course Collins' paper [5]. But I am unable to find actual
performance data of the different circuits. Does someone have
such data and would share it with me/us?
I modified my TAPR TADD-2 to let one output driver be driven from the
clock input circuit. Driving it from the 5 MHz sine out of a OSA 8600
BVA gave me 2 ps of jitter on the DTS-2070C, which is about as low as it
ever goes, so more or less at it's noisefloor. Not to shabby.
Bruce will probably be able to measure it up before me, as I'm in
Washington DC right now on travels, but I should actually do that
exercise as I get home.
As you have 5 MHz, there isn't very deep Collins squaring needed.
Cheers,
Magnus
