Part Number: TLV320AIC3104-Q1
Other Parts Discussed in Thread: TLV320AIC3104

Hello，

One customer from DIDI liked to confirm  if  TLV320AIC3104 could output three sound source simultaneously  with TDM mode?

He used DINL and DINR input two channel 16bit serial data and would like to output three output of the blue circle simultaneously. 

Best regards

    Hi Kailyn,

    All outputs can be used simultaneously. Using register settings, you can route either DAC L, DAC R, or both to any or multiple outputs.

    Hi Jeff McPherson，

    Thank you very much for your reply. I think you misunderstand the meaning, the customer  used DINL and DINR input two channel 16bit serial data, he would like to confirm if four speakers play four different music at the same time and time-sharing .

    Best regards

    Hi Kailyn,

    There are only two DAC channels, meaning it's not possible to play 4 different music tracks. All four outputs can be used at the same time (LOL/R and HPL/R) but the user must choose where the two input channels are played from. 

    Also to clarify, DINL and DINR are one channel each, meaning the device can only receive two channels of audio data.

    Best regards,
