TDA7801

I2S bus interface

The TDA7801 accepts the I2S standard format that could be time division multiplexed

(TDM), however the WS still needs a 50% duty-cycle to work correctly. The Figure 34 shows

the different I2C settings allowed for the I2S interface (2,4 or 8 channels transmission on a

single serial data line (SD) can be selected). By I2C programming it is possible to choose

between the following interface settings:

channel 1 and channel 3 channel on SD1_3 and channel 2 and channel 4 on

SD2_4

all four channels on SD2_4. SD1_3 has not function.

eight channels transferred on the SD2_4 line. This setting is feasible in the

PowerSO36 and Flexiwatt27 package.

Figure 34. TDM setting

The TDA7801 accepts the I2S standard format with a bit clock (SCK) equal to 64 fs.

Note, TDM setting is guaranteed for a maximum Fs = 96 kHz.
