Stm32L4 at 80Mhz

Hi,

I am using an Stm32L4 microcontroller in my Design, and want to be able to run it at up to 80mhz, but can't find any example on how to achieve this with an external crystal. The datasheet says the maximum frequency for an external crystal is 48Mhz, so I think I have to apply the correct prescaler for the 80mhz.

The other question is the correct Crystal for that task, can I use any or do I have to watch out for sth?

Currently I plan to use the Abracon ASFL1 with 32Mhz, would this fit?

 

Greetings

 

Michael
