Hi,

is it possible to generate 24 MHz and 6 MHz signals (50% duty and in phase) with 12 MHz signal with shifted phase and reduced duty somehow using Kinetis microcontroller? Preferably with min. count of timer modules as we need one or two timer modules to be used for another purpose than generating this waveform?

Please see image.

Hi, Martin,

Do you want to generate 24MHz and 6MHz signal with 12MHz signal or generate 12MHz and 6MHz signal with 24mHz signal?

If you want to generate 24MHz and 6MHz signal with 12MHz signal, it is impossible without FLL or PLL.

If you want to generate 12MHz and 6MHz signal with 24mHz signal, it is okay with FTM of Kinetis(K40/K60/K20/K10...) or eFlexPWM(KV family).

Hope it can help you
