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.
