ADAU1452 CLKOUT capabilities

Dear,

I plan to integrate an ADAU1452 DSP.

In the data sheet is a passage about CLKOUT capabilities of the DSP.
"The CLKOUT pin can drive more than one external slave IC"

I would use the CLKOUT to drive 3x CS4398 D/A and 1x CS5361 A/D. 
They are all on the same PCB near to the DSP.

Is it recommend to use a CLK Buffer in this constellation (any recommended
ICs?) or is it just fine to feed these A/D and D/As directly from the CLKOUT
Pin?
Or should I use an external oscillator to feed all of them.

Thanks for your support!

 

kind regards
