Mario, Decoupling power line of oscillators is almost mandatory. A lousy power line will degrade severely the phase noise. Decoupling might vary with frequency used. I'll suggest 1 microFarad in parallel with 10 nF. But that's just me. Good luck with your design, Jean-Paul N1JPL On Dec 2, 2017 1:20 PM, "Electron" wrote: > > Hello, > it may seem a banal question, but as it's the first time I use an externa= l > oscillator (with integrated crystal), I am not sure.
