Thanks for the input, do not forget the total system cost has to be $200, the latest version has a simple VCO but I would like to eliminate component selection, may stay with the present design, but the Cirrus CS 2300 followed by a bubbler may be the answer. Maybe there is something like the 2300 out there that goes to 100 MHz in a package that normal time-nuts (if there is such a thing) can solder. Bert In a message dated 2/25/2011 9:33:43 A.M.

Just randomly.. A Vectron TX400 has a +/-12 ppm tuning range on the EFC input.. that's about 1200 Hz... http://www.vectron.com/products/tcxo/tx-400.pdf Digikey shows a whole bunch of Crystek VCOs for around $20-30 _______________________________________________ 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. _______________________________________________ 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.
