Apr 04, 2019 . TDM for 16 audio channels. What's the best way? We have an application that requires 16 independent bidirectional audio channels, and I'd prefer to do it with as few wires as possible. I see that the AD1938 can handle up to 8 inputs and 16 outputs in daisy-chain mode so in theory we could do it with four of those,but I read int he data sheet ...

The TDM interface has not been standardized and there can be variants between the TDM formats. Fortunately the TDM ports in DSP devices are programmable and will support the multitude of options.
The Serial Audio Interface is by far the most common mechanism used to transfer two channels of audio data between devices within a system; for instance, from the analogto-digital converter to the Digital Signal Processor (DSP) and then the digital-to-analog converter, as shown in Figure 1. The Serial Audio Interface
The complexities involving signal routing and providing a sufficient number of input/output ports on digital-signal-processors and converter can be a daunting task. As a result, the industry has adopted a Time Division Multiplexed (TDM) interface that allows multiple channels of data to be transmitted on a single data line.
