Interesting. Maybe not the optimum oscillator for a GPSDO. Lars
>Från: Tim Shoppa<mailto:tsho...@gmail.com> Skickat: den 14 september 2016 14:39 There are special "wide-pull-range" VCXO's where a 10MHz unit will indeed have sensitivity of 600Hz/V or more. e.g. http://www5.epsondevice.com/en/products/vcxo_standard/vg4231ca.html I don't know exactly what Epson does inside that particular unit, but a trick to get wide pull range with discrete circuits is to put two or more crystals in parallel.
