Minimum output frequency for ADF4351 is 35 MHz with %50 duty cycle. It is not the right part for your application. Your application requires a timer. You can check TimerBlox products from below link.
I think what you need can be done by using LTC6991. You can use TimerBlox tool from the following link.
I created an example using TimerBlox tool as below. You can change the values according to your requirements.
