TMS320F28377S: Can the PWM clock run at 200MHz?

Andrew Barnett

Part Number: TMS320F28377S

I have an application where it would be beneficial to run the PWM clock at 200MHz, as opposed to the 100MHz baseline (ClkCfgRegs.PERCLKDIVSEL.bit.EPWMCLKDIV= 1 with a 200MHz SYSCLK).

If I set ClkCfgRegs.PERCLKDIVSEL.bit.EPWMCLKDIV to 0 with the 200MHz SYSCLK the pwm clock will be 200MHz. What are the detrimental effects of doing this?

Thanks in advance for any insight.

Andrew,

200MHz clock for PWM is not supported on this device and it will be difficult for us to provide the risk with using that option.

Thank you Vivek. Is there a similar device that does support a 200MHz PWM clock?

Hi Andrew,

We have new device F2838x which support 200MHz PWM. This device has additional feature compare to F2837x. You can find the detail of this device here. Currently samples are available for development only and production release is planned by end of this quarter (Q2 2020).
