Hello

 

I have two questions about both ADF4351 & ADF4355-2 PLLs:

  1. What is the highest frequency resolutions these devices have? and can it be below 1Hz?

         In other words, can we produce an output frequencies of 50.000000MHz & 50.000001MHz,

                                                                                                    26.000000MHz & 26.000001MHz

  1. Are there any more phase noise graphs with Loop filters having higher BWs?
  2. Are there any more phase noise graphs with Loop filters having lower BWs?

 

BR,

Alon
