Other Parts Discussed in Thread: TLV320AIC3263

Hello 

                Customer would like to 3 I2S channel and output TDM format audio to Nvidia Tegra 1 CPU side. Could we use multi AIC3263 for daisy chain topology  to implement these function ?

    Hi, Patrick,

    The TLV320AIC3263 is able to use the TDM mode to send multiple channels with a similar pin (DOUT). However, these devices don't support daisy chain. The TDM mode uses the DOUT pin of multiple devices. All the DOUT pins must be connected to the similar point. If my understanding is correct, the daisy chain connects all the devices in a sequence. DOUT pin should be connected to the next codec. This operation is not possible on our codecs.

    Please let me know if you have more questions or comments.

    Best regards,
