Almost all of them have just a just pins on their connector, ground,
power (one or two voltages) and "control" with is a variable voltage
to apply and the ooutput frequency varies over a small range that is
proportional to the input voltage. The exact ratio of Hz/V is device
dependance.
Typically to "discipline" an OCXO you use a DAC to drive the control
voltages. You would use a micro controller to look at some kind of
phase detector and adjust the DAC.
The T-Bolt is nice because all this is done for you in a low cost self
contained unit. But you don't learn much that way, except how to
connect cables.
