More ways than you could imagine... IMHO, a 100MHz PLL is likely to give the best results, and is very easy to implement. A 100MHz crystal oscillator should give very low phase noise and spur levels; crystals are readily available and there are quite a few circuits around. Crystal oscillators running at 100MHz or so are widely used by radio hams for multiplication up to microwave frequencies so the phase noise and spur levels has to be low to start with, which a VCXO can achieve. Crystal oscillators can easily be disciplined with a varactor diode. Various PLL configuations exist to do this and the loop bandwidth is very narrow so the phase noise will not be degraded significantly by the PLL. There are other ways as well, but my vote would be for the VCXO as above. regards Grant _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
