Here's the blog post that shows the bad quality of a (pretty expensive) Oscilloquartz 8663 OCXO: https://www.paulvdiyblogs.net/2023/07/building-10mhz-master-... "Lastly, I'm not going to use the Oscilloquartz reference voltage to power the frequency setting circuit. It seems the logical thing to do, but this so called reference voltage is anything but a reference voltage. They are typically created by using a zener (reference) diode like the TL431, but that is simply not good enough as you will see." |
