3x TLV320AIC3204 Sample synchronized

Other Parts Discussed in Thread: TLV320AIC3204

Hi,

My design has 3 TLV320AIC3204 codecs that each connect to 2 microphone preamplifiers in single ended mode. I need the 6 microphone signals to be sampled in sync. Just connecting the same MCLK is not enough due to the fact that the PLL of each codec is programmed one after the other. 

How can I get the samples taken in sync? 

Thanks!
