Hi,

 

I have some questions about ADF4158:

 

 

1.According to the Evaluation Board User guide, there are a passive loop filter. Is that for bandwidth 20kHz?

 

2.How to design the bandwidth of  Loop filter (R,C Value) I want?  I'm wondering is there have any tool to calculate? or formulas which need some specific parameters to calculate?

 

3.Pin RFINA, RFINB are differential pair or not?

 

I really appreciate your help.

 

Regards,
Howard
