I'm using the codec ad1934 to have 2 channels with I2S protocol but I can't find several informations in the datasheet. I'm using a 16,934 mHz crystal oscillator for the mclk but it doesn't run. All the register values are at 0x00. What should be the value of bypass capacitor of the quartz? How can I adapt the quartz if an other sample frequency is needed? Can you help me to solve this issue? Thank you a lot.
