ADF4351 prescaler

Hi,

 

can I use the 8/9 prescaler when the feedback frequency is lower than 3.6 GHz?

See example below:

   

f_ref80MHz
D1
R5
T0
f_PFD32MHz
f_VCO2440MHz
MOD320
Prescaler8/9
INT76
FRAC80
Output_DIV4
f_RF610MHz

 

Is there any pros/cons in using the 4/5 prescaler instead?

 

Thanks

 

Regards
