How to retrieve 8MHz from 168 MHz processor

I've got STM32F407VE controller that works at 168 MHz. I need to get a 8 MHz clock frequency from it and I guessed to use a timer in PWM mode, but they all have a 42 MHz or 84 MHz clocks and so I can't use approriate divider for desired frequency. How can I get this frequency from the controller?

Oops, sorry. It is just an clock frequency to timer's periphery and I can use a half of CPU working frequency. I just ran the controller on 160 MHz and it looks well.
