Dear all,

Currently, I'm digging the ADF4159 Evaluation board with some specification and software program. Unfortunately our hardware and RF engineer resign the company without no message, But I've got a little bit knowledge to prove the output of ADF4159 frequency output.

 

Basically from the ADF4159_setting_250us_triangular.txt. I'd like to have every register set from 250us to 500us by 1us unit.

 

So I have 2 kind of questions,

 

1.Can we calculate the output frequency with the below setting values?

 

 

I'm trying to understand the output of frequency, but it's quite a bit hard to me. So Would you please help me how to calculate or estimate the output frequency from above setting value?

 

2. I need every register set from 250us to 500us by 1us unit. But I can't do this because the rack of knowledge, so Would you mind help me to get the register set ? what am I supposed to do if I want to get 251us and 252us  253us...,500. register set?

 

Thanks 

Sincearly,
