I designed my own board around ADF5355, depending on the evalution board EV-ADF5355SD1Z.
When observing the output of the ADF5355, we found that the frequency is mostly unstable and change slowly with time, as depicated by attached video.
I thing the problen related with TCXO I used, "fox924b 20MHz"
If my analysis is right, what is optimal TCXO shoud I use.
Thank you in advances.
