We are using the STM32F746 in combination with an exernal SD-RAM.

The clock rate for the RAM is set to a frequency of 96 MHz.

At radiated emission measurement we are above the limit line at 192MHz (double RAM clock)

Is there a possibility to activate jittering or any other option to reduce the radiated emmisions of the electronic system?
