TLV320AIC3204: Clock source for initialing AIC3204

Part Number: TLV320AIC3204

Hi Sir,

 My customer is design AIC3204 but their host can't read AIC3204's I2C address (0x30). Does AIC3204 need clock (MCLK or...) as reference clock to process I2C communication? Or any point we have to check if AIC3204 is not ready to work? Thanks for your kindly help.

Best regards,

Gary Tengt

  • Hello Gary,

    Thank you for reaching out. The TLV320AIC3204 will respond to the I2C address of 001 1000 (0x18).

    Is the customer using an EVM? I2C address 0x30 is the correct address for the USB to I2C bridge that is on the EVM.
