If there is no datasheet to refer to then the usual value is between 10K
and 20K.
10K is the most common value for 5V or 8V Vref. The OCXO should provide the
Vref output pin to connect one side of the pot, the other to GND, for a GND
referenced EFC. Your mileage may vary but, without a datasheet, it is the
best starting point.
