MCLKIN & BCLK synchrony in ADAU1701

I'm try to design an I2S communication system with a uC and ADAU1701.

uC has to be master in I2S and obtain the digital audio from ADAU1701.


ADAU1701 has an crystal of 12.288MHz as source clock, because fs=48KHz.


In order to use Audio Digital Output from ADAU1701, the clock signal MCLKIN of dsp and BCLK from I2S master, needs to be synchronous.


How do i reach synchrony between MCLKIN of ADAU1701 and BCLK from uC?
