Number of frequency change in PLL synthesizer (ADF5610 or ADF5356)

  Hello!

It’s supposed to use a PLL synthesizer with VCO (ADF5610 or ADF5356),

and a frequency changes will several thousand times per day. Are there any restrictions on the number of frequency changes per day or the total number of data load operations in internal memory? Or useful life depends only on reliability data? 

Thanks!

Sincerely,

Kirill
