adf4158 timer

Hello,

 

I am currently using the ADF4158 to generate continuous sawtooth ramp.

To post process my data, I need to be sure ot the different timings in my frequency ramp.

As I simulate the data I computed in ADSIMPLL, I do not understand something:

My PFD clock is 10MHz, my CLK1 is 100, my CLK2 is 1, and I have 3000 steps. My ramp duration is 30ms.This shoud give me a timer of 10us.

On the simulation result, I obtain a time between each frequency hop around 30us.  As a consequence, I do not have the good number of steps? What did I miss?

 

Thanks for your answer,

 

Regards,
