I am need make a prescaler with 64/128/256 prescaling from ADF4110 or ADF4111 from MUXOUT output

 

I get register values from ADI Int-N PLL software for ADF4110 and N=128 (this is 128 prescaling rate?)

 

R=0x14

N=0x201

F=0xcd80a2

 

After I load this in ADF4110 with CE initialization method, but nothing signal on MUXOUT when i put 430 MHz in RFinA

 

I dont put REF frequency to ADF4110, she need this?

 

I am Ukrainian and my English is bad
