Can I make ADF41020EB1Z work with an external VCO?
There is my experimental plan.
Firstly, VVCO 0V so that VCO of ADF41020EB1Z does not work.
Secondly, use EXT_VCOOUT as RFin (the output of the external VCO).
Thirdly, use external signal source as REFin.
Lastly, use VTUNE as Vout (the input of the external VCO)
