AM2732R: Question about VCLK4 to EPWM

Chris Meng

Hi,

I would like to know the max clock for VCLK4 to EPWM. I can't find detail clock source for VCLK4 in TRM. Would you pls kindly help?

Thanks,

Chris

Hi Chris,

I am checking with our design team for this information. I'll have an answer shortly.

Thank you,

Hi Chris,

The ePWM is clocked from the SYSCLK (system clock) which would provide a maximum of 200 MHz for the PWM output frequency. However, the LVCMOS IO used on AM273x have a maximum frequency of 180 MHz, so these will practically limit the frequency.

Thanks,

-Randy
