[GPS_Standard] Requirements: a low jitter Sine to Square-wave circuit

[David Garnier]

Hello,

I have not thought this question out completely but maybe someone
more knowledgeable on PLL's or interfacing sine-wave oscillators to
TTL interfaces could answer these basic questions.

I have a Isotemp OCXO 134-10, 10 Mhz sine wave oven oscillator
http://www.isotemp.com/docs/OCXO134-10Spec.pdf

1) I need a Sine wave to TTL (circuit or IC) to interface this oscillator
to an existing high quality RF signal generator. 

_Question._ It seems to me that this application would require a "low 
jitter"
sine to square-wave circuit. But, wouldn't the PLL in this RF signal 
generator
filter out this added jitter?

2) _Inside the loop of a disciplined GPS oscillator_, is it less 
critical to have
a "low jitter" sine to square-wave converter?  ((Does the excess jitter 
in this
converter "come out in the wash" being within the disciplined GPS 
oscillator?))

3) Measuring pico-second jitter isn't trivial.  Any ideas on how to do 
this easily?

4) Maybe these questions cannot be initially answered but need elaborate
"jitter measuring equipment" to make these determinations?

5) There's some lab equipment available that maybe could help answer this
question - but this is vacation time!!!

Thanks in advance for any thoughts you have on the subject.

Regards & 73's
