Spread Spectrum (SSCG) and USB on STM32F429

Question asked by frank.matthias on Jul 4, 2017

Hello everybody,


i want to use Spread Spectrum on the STM32F429BIT but i want to use USB too.


Is there a possibility to run the USB on a clock without Spread Spectrum?


For example the STM32F446 has the option to choose between PLLQ or PLLSAIP.
