Nigel, Yes, you understood and answered the question.
Thank you Don O I don't know if I've misunderstood your question, but as I understand it the voltage reference output is a fixed voltage from an internal regulator that can then be used as the supply to an external control circuit. For example, it could be used as the feed voltage for a variable resistor that has its wiper connected to the EFC input to allow for manual frequency adjustment. When some other form of external control is used, such as a DAC output for example, it's not uncommon to find the voltage reference output left disconnected and the control circuit fed from an alternative supply.

Is it necessary for the DAC output / frequency control input, to track this voltage reference output? _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
