ADF4351 RF power-down switching time

Dear all,

 

In my design I would use the RF Power-Down function of the ADF4351 in order to enable and disable the RF output of the synthesizer by means of a hardware control on PDB_RF pin.

My question is, what is the switching time of output signal using this functionality?

Moreover, what is the output signal suppression level?

 

Regarding the ADF4351 RF output, what is the impedance of the output when it is OFF.

 

Thank you in advance for your reply

Luca
