Does anyone have any knowledge of a simple (just soldering a few connections
and maybe programming a hz/volt rate) PCB for synchronizing a precision OCXO to
a GPSDO? I am trying to improve short term stability with a high stability
OCXO and dont want to cut into my fury and replace the OCXO.

This is something I would also like to know. I'm sure many others
would be interested as well. Bert would it be possible for you to
share your thoughts on the matter with the group at large?

Tried, no interest, some one has offered to in the future do a gate array
version, you may want to wait for that I am in the mean time using am analog
loop for less than 100 seconds between Rb and OCXO and a very modified
Shera for GPS/Rb. Works for me.
Contact me off list and we can talk.
Using the PPS as a sync source?

The Vectron TRU-050 is a PLL with an integrated VCXO. You can sync a 10MHz
OCXO but not from a GPS receiver with the PPS only.

Or if you want a better PLL than just an XOR gate, use a 74x4046.
They are still available in DIL, so building a complete PLL is possible

I am patiently waiting for the code to drive the DAC.

Regarding the vectron tru-050 looks nice but requires me to come up with
a board and resistors and capacitors etc which is above my ability.
Uhmm... how far does your abilities go?
I looked at the miller thing but
OK, so 1 PPS GPS to Rb - need a TIC; 10MHz Rb to OCXO - need a PLL. Are
you interested in an all digital 10nS single shot TIC that gives you a 2's
complement number (negative at the left of the GPS PPS and positive at the
right)? Here it is. This is my TIC, I use it on all my GPSDOs.

Regarding my abilities.. regarding electronics... poor soldering is about
my limit... through hole only. That is why I was hoping there was some
off the shelf method that I could wire up with 10 MHz in from the gspdo and
from the oscillator then wire up the EFC volatge and set the required
I'm running (although running isn't quite correct for VHDL) this on a

than local clocks, which are usually discouraged) property. Of course this
