AM2434: max EPWMCLK on dsp and/or Sitara

Part Number: AM2434

Hi,

for example on F2837x dsp family the EPWMCLK should not exceed 100 MHz, giving a 10ns resolution on PWM prd if not using HR.

On F2838x, this limit is 200 MHz. Which is the limit on Sitara devices that uses the same ePWM peripheral? (like the AM243x family)

And, in general, there are devices where the EPWMCLK could be > 200 MHz?

thank you

Alberto

  • Hi Alberto,

    Apologies for delayed response. From their respective TRMs, I could find the following.

    • for AM263x, AM263Px the EPWM Clock can be as high as 200MHz, SYSCLK (source)
    • for AM273x, the EPMW Clock can be upto 100 MHz (VCLK4 source)
    • for AM243x, the EPWM Clock is sourced from PLLCTRL0 as MAIN_SYSCLOCK0/2

    Thanks and regards,
