ADF4350 with integer-N

hi,

when using ADF4350 with INTEGER-N divider, the "prescaler (4/5 - 8/9)" is still active ??

 

in other words:

 

ref 10MHz

PD 10MHz

 

freq: 3500 MHz

-----

N should be 350 ...

 

How set 350 to "N" divider ?   -> "INT" = 350  ..  "FRAC"  = 0 ..  "MOD" = 0   .. "OUT DIVIDER" =1   ?????????????

If yes, the "PRESCALER BIT" in R1 must be set or clear ????????? 

 

i am confused and the datasheet is not so clear about the "prescaler" ..

 

many thanks in advance

 

best regards
