TDM OPERATION BETWEEN THREE OR MORE DEVICES
The AIF operation described above illustrates how multiple audio channels can be interleaved on a
single TXDAT or RXDAT pin. The interface uses Time Division Multiplexing (TDM) to allocate time
periods to each of the audio channels in turn.
This form of TDM is implemented between two devices, using the electrical connections illustrated in
Figure 43 or Figure 44.
It is also possible to implement TDM between three or more devices. This allows one CODEC to
receive audio data from two other devices simultaneously on a single audio interface, as illustrated in
Figure 53, Figure 54 and Figure 55.
The WM8281 provides full support for TDM operation. The TXDAT pin can be tri-stated when not
transmitting data, in order to allow other devices to transmit on the same wire. The behaviour of the
TXDAT pin is configurable, to allow maximum flexibility to interface with other devices in this way.
Typical configurations of TDM operation between three devices are illustrated in Figure 53, Figure 54
and Figure 55.
