Sep 01, 2014 . The TDM interface is by far the most common mechanism used to transfer multiple channels of audio data between devices within a system as shown in Figure 1. 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 …

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 device provides a PCM interface for audio data and a standard I 2 C interface for control data communication. The PCM interface supports audio playback using I 2 S, left-justified, and TDM audio data formats. A unique clocking structure eliminates the need for an external master clock for PCM communication, which reduces pin count and ...

The Automotive Audio Bus (A2B®) provides a multichannel, I2S/TDM link over distances of up to 15 m between nodes. It embeds bidirectional synchronous pulse-code modulation (PCM) data (for example, digital audio), clock, and synchronization signals onto a single unshielded twisted pair (UTP) differential cable. A2B supports a direct point to point c

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.
Both ICs support 8 channel time division multiplexed (TDM) data. The digital audio interface accepts specified sample rates between 8kHz and 96kHz for all supported data formats. The ICs can be configured to produce a left channel, right channel, or (left/2 + right/2) output from the stereo input data.
The digital audio interface automatically recognizes up to 35 different PCM and TDM clocking schemes which eliminates the need for I2C pro- gramming. Operation is further simplified by eliminating the need for an external MCLK signal that is typically used for PCM communication.
The device supports time- division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with either the I2C or SPI interface. Additionally, the PCMD3180

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.
