ADSP-BF52x Oscillator Frequency

Hello, I am having some trouble selecting the frequency of the Crystal (or Oscillator) for a Blackfin 527.

I need to use the ethernet MAC in RMII mode, does this mean i need a 50MHz clock?

I also need to use the SPORT and UARTs.

I've been told I need to be careful when selecting a clock, so that the dividers allow all the peripherals to clock at the right rate. Is this correct?

We would also like to be able to slow the core clock frequency to save power.

Does any one have any recommendations on clock frequency?

 

Thanks.
