Implementation of PWM in the IMXRT1176 controller

Jeevan — Wed, 10 Jan 2024 11:44:31 GMT

Hi team,

We are using IMXRT1176 controller in our project and we want to implement a pulse width modulation which is capable of generating pulse waveform of 40 nano second period continuously with 50% duty cycle.

Is it possible in the above-mentioned controller in any one of the 4 PWM modules present in it?

Hi,

Thank you so much for your interest in our products and for using our community.

The eFlexPWM is driven and limited by BUS_CLK_ROOT and the output frequency of this clock must be lower or equal to 240MHz.

Hope it helps you.

Have a nice day!

@_Leo_ For 240 MHz, the time period will be 4.16 nano second. Is it correct?

So, it is possible to achieve the time period of 40 nano second period PWM wave is what you are trying to convey I believe.

Yes
