Recently I used the BF518 to control two AD1934 to play audio through TDM mode.Last ad1934s can play in 8 channels. Could you give me some examples? Like this picture.

Hi,

You are showing the Dual-line Daisy Chain TDM data flow here, which is used for high speed multi-channel TDM configurations. Can you be more specific about what you kind of examples you would like to see? Schematics? Register settings? I will need some system information from you: how many channels and what sample rate will you be using? What MCLK frequency will you be supplying?

Best regards,

Coleman

See figure below. It is our part schematic. I want a reference schematic, and the best is that the register settings. I will use 8 channels. The sample rate is 44.1khz or 48khz. And the MCLK frequency is changed according to the sample rate. 12.228Mhz or 11.2896Mhz. Can you help me give me some similar example?
