I have a FRDM-K64F board, and working with KDS 3.0.0 and KSDK 1.3.0.
I'm looking for a solution - sine wave frequency 4-6 MHz and amplitude 450mV.
Is implementation examples or how to implement?
Thank you in advance.
The MK64FN1M0VLL12, that is available on the FRDM-K64F board, contains two DAC devices. But these modules are not able to produce 4-6MHz sine wave amplitude (see the DAC specification in the MK64FN1M0VLL12 datasheet).
You can use PWM (FTM device in the PWM mode) to produce 4-6 MHz square wave output that can be filtered by an LC (or RC) filter for generating sine wave output. In this case, you can use fsl_ftm or Init_FTM component and use one of the FTM channels in PWM mode (edge aligned mode) for generating of the signal.
