Using TDM Function to Interface Four AIC33 CODECs with a Single Host Processor

This application report discusses how to use the TLV320AIC33 audio data port's time-division multiplexing (TDM) function to connect interface and run four TLV320AIC33 codec devices simultaneously under the control of a single host processor. Four TLV320AIC33 EVM boards and one USB-MODEVM board were used to test the interface and function.
