Bill, this would be a good question for time-nuts (CCd here). I don't know what slope your particular oscillator has, but if it is negative then years ago someone posted schematics on how to invert the slope and how to offset the EFC voltage and change the range etc using an Opamp.. That should be in the archives. Otherwise such circuits are pretty readily available in the application notes of TI, LT, National, etc etc. bye, Said In a message dated 11/18/2014 15:54:30 Pacific Standard Time, [email protected] writes:
I guess my idea of controlling a 10811 with the LTE-Lite is dead as its EFC has a negative slope. Any ideas? Regards, Bill On the 10811, that OCXO can typically be mechanically tuned to have a 1.5V nominal EFC set voltage. The LTE-Lite can drive from 0V to 3.0V EFC, so that should be more than required on a good (well aged and good thermal stability) 10811. We have not tried driving a 10811 with it yet though, so can't say for sure. One requirement is that the OCXO has a positive EFC slope.

What are your ideas on using it to control a 10811 instead of the built in 10 mhz osc? Will there be enough control voltage for the 10811? ____________________________________ (http://www.avast.com/) This email has been checked for viruses by Avast antivirus software. _www.avast.com_ (http://www.avast.com/) _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
