AM2634: EPWM With Varying Duty Cycle In Every Switching Cycle

Tool/software:

Hi experts,

I wanted to generate 1.25MHz PWM in which duty cycle is varying in every switching cycle.
I am using "epwm_hr_duty_cycle" example and i am able to generate the PWM with varying duty cycle in every switching cycle till 600KHz but not able to generate the at 1.25MHz.

   

      fig1. oscilloscope screen-shot for 630KHz epwm( each switching cycle with variable duty cycle)

                              fig2. Oscilloscope screen-shot for 1.25MHz epwm



 Please help in resolving this issue

Thanks and regards
