Dears.
The LM2592 is designed and tested.
Please review our issue.
I changed the frequency by unlocking at 6Ghz.
When it is changed to 400MHz step, it locks up to 4.8GHz.
From 6.8GHz, it is locked again.
I tried modifying the bypass cap and loopfilter but the symptoms are the same.
Below is the value controlled through the GUI
