Hi,

 

We are using ADF4360-2 for production design, but we found a few device can not be locked well when OFF/ON its power supply.

We found changing value of Cn (=10uF which is recommended in datasheet) into 4.7uF can improve the issue and properly start up and lock the pll.

I would like to send you schematic and other related settings but prefer to be in closed loop. Could you please let us know contact point who we should talk to ?

 

Best Regards,
