I2S Output Mux When two smart PA is connected and TDM mode is used. At this mode, the frame length should be set to 128bit. The SDI signal is only 16bit available for each channel. The minimum LRCK length is 2 BCK length. The sequence is shown as below : BCK DATAI LRCK Device0 Data = 64bit Frame Lengh = 128bit Audio Data = 128bit DATAO Device0 VMON Device0 IMON Device0 IF, VBAT Device0 SPKPROT_GAIN Device0 VTEMP Figure 13. One Smart PA TDM Standard Format The TDM_TX_LOC register indicates the starting slot to put the data stream on SDOUT pin and the TDM_TX_LEN whose unit is byte (slot) determines how many bytes will be transmitted. Please refer to the TX Data Structuring in I2S Mode section. BCK DATAI LRCK Device0 Data = 64bit Device1 Data = 64bit Frame Lengh = 256bit Audio Data = 256bit DATAO VMON IMON IF, VBAT SPKPROT_ GAIN Device0 DO Device1 DO VMON IMON IF, VBAT SPKPROT_ GAIN Figure 14.
