Hello.

 

I need ADF4110 with the turning off VCO in my design.

The reference frequence is always on.

ADF4110 is programming once at initial power up. Registers:

1F8093

000800

064005

 

After VCO power-up I see on oscilloscope that the regulate of control voltage is delayed on random time.

How do I reduce and stabilize the lock time?

 

Thanks in advance.
