Thank you for the link. The data sheet raises a few questions:
The sine wave input level is specified as "1Vrms nominal 0.5V Peak to
peak." Of course, 1Vrms is ~2.8Vp-p. It is not clear what this

Hi
Lots of choices:
1)do you need 1 pps distributed?
2)do you need 100 KHz, 1MHz, 5MHz (or really odd frequencies) for anything?
3)how many 10 MHz gizmos

Hi
You *can* get the job done with a CMOS inverter biased up and filtered. An op
amp is likely not as good as the full bipolar approach and may be better /
worse than the gate depending on exactly what you are looking at.

Hi
There are a number of discrete transistor buffers that have very good
isolation and short term stability / phase noise performance. I'd take a
look at the one from the NIST papers and Bruce's more modern re-design. All
are in the archives. http://tf.bo

Bob and Paul,
I have at moment 6 equipment's maximum which I want sync with 10MHZ only.
The video distribution is an idea but the kit from Ve2zaz have other way but
the problem is the isolation.
I have 2 independent Nortel GPSTM but I don't need redundancy for the job.

Hi,
At the moment my GPSTM have 1.3e-012 in alan deviation and it's time to
connect to the equipements.
Which is the best way to do it?

This topic has been covered many times.
The answer that seems simple fast and efficient is to use video
distribution amplifiers from the analog tv market.
There are many other ways to also do this job. Depends on your ability to
home brew.
But search time nuts and you will see these types of thread
