STM32 MCO1/2 Driving a second chip XTAL input

Hello all,

 

In my project, I'm using the STM32F411CEU6, with a 9.6MHz External TCXO as a clock source. I would like to use the same clock to feed another chip in the board.

I was thinking of using the MCO1 or 2 in order to rout out the 9.6MHz to the other chip.

The other chip XTAL input characteristics are:

Can MCO1 or 2 drive an input load of 150k / 20pF @ 9.6MHz?

 

Thank you all,

Chen
