Hi team,
We are evaluating a system which will implement more than 2 microphones when our host only has one channel I2S interface. In my study, it looks TDM mode can achieve this application while our host processor supplier told us DSP mode can be used. After looking at TLV3254 datasheet, it looks both TDM mode and DSP mode can be supported. Then I also checked “TLV320AIC3254 Application Reference Guide” but only left justified, right justified, I2S and DSP mode are introduced without TDM mode in section 2.6. It seems to me TDM mode is similar to DSP mode. Can you help explain what is the difference between them?
Thanks.
