PWM Clocks on C2000?

Other Parts Discussed in Thread: TMS320F28035, TMS320F28027

The question I have is about the PWM clocks. I have not been able to determine what the clock frequency is. It appears from what I have read it can be anywhere from sub CPU clock to over 6GHz. What is the max PWM clock that I can run? Right now my design uses 128MHz, but if this part can do better, then that makes sense. Thank you in advance for your help.

Still not sure of the specific part number, but I will use the TMS320F28035 as an example.

In the datasheet of the TMS320F28035, Figure 3-9 provides an illustration of the clock source for the ePWM peripheral module to be the SYSCLKOUT, which is the CPU clock. Therefore, on the TMS320F28035, this can run up to 60MHz.

For the TMS320F28027, the same type of illustration is provided in Figure 3-10 of the datasheet. Again, the ePWM peripheral module input clock is SYSCLKOUT.
