TLV320AIC3254: Clock requirements for miniDSP processing

Part Number: TLV320AIC3254
Other Parts Discussed in Thread: STRIKE

Hi there. 

Is there any information out there that relates the necessary clock requirements for the DAC_CLK and ADC_CLK with the amount of processing being done by the 3254 and the sample rate? 

Am I correct in assuming that these clock speeds must be greater than the miniDSP_A/D_Cycle number * sample rate? 

I see there are limits to the miniDSP clocks of around 55Mhz which therefore puts a limit on the processing the 3254 can do.

So would a higher sample processing rate of 88.2kHz or 96kHz be possible with a lower number of miniDSP cycles? 

How can we strike the best balance between power consumption and processing?

Thanks in advance for your reply.
