iMXRT1064 ADC asynchronous clock frequency?

I have a question pertaining to the asynchronous clock source in the ADC peripheral of the iMXRT1064 (ADCx_CFG.ADICLK = 11b). The reference manual states that the asynchronous clock is “generated from a clock source within the ADC module”, but what exactly is the value of fADCK if I choose this clock source? I’d like to know what value it is for purposes of calculating the conversion time.
