Positive update, in the broken unit
the pin 10 goes to power module input,
while the pin 8 goes to power module
ground, and there is grounded.
I powered the good unit and
it locked in few minutes, wothout driving
the EFC, the frequency seem very near
the FE5680 I set against the GPS.
The output 10MHz phase is influenced badly
by input voltage up to 18V, and is
stable after that, so the unit seem
to be a 19-32V one.

Now that the failed unit is still opened,
I will try to check the inner working
voltageon this, if anibody has any question
or curiosity about the units, I still have it
opened up...
