TDA7808

I2S and TDM bus interface

7.2

I2S input data format

The TDA7808 accepts I2S standard interface format as in Figure 26 and the I2C bit

configuration is IB3 [D5,D4,D3] = "000".

Figure 26. I2S format

7.3

TDM input data format

TDM 4-channel is allowed for TDA7808 and it is as in Figure 27. All the channels are sent

on the audio data line SD24. The channel's order is 1, 2, 3 and 4. The I2C bit configuration is

IB3 [D5, D4, D3] = "001".

Figure 27. TDM 4-channel format

TDM 8-channel is also allowed and two devices (device 1 and device 2) can be driven by

using just one serial data line SD24. There are two selectable options

When IB3 [D5,D4,D3] = "010" device 1 is first sent; when IB3 [D5,D4,D3] = "011" device 2 is

first sent. In Figure 28 TDM 8-channel format is showed.
