INTERFACING TO THE DIT4096 DIGITAL AUDIO
TRANSMITTER
The Texas Instruments DIT4096 digital audio transmitter
encodes linear PCM audio data into AES3 standard
formatted data, which is compatible with a number of
professional and consumer audio specifications and
interfaces. This encoding provides a convenient, standard
transmission format over which the audio data from the
PCM4201 may be carried. The physical interface may be
twisted pair or coaxial cable, or all-plastic optical fiber. The
combination of the PCM4201, the DIT4096, and the
appropriate microphone element and preamplifier circuit
may be used to create a cost-effective, digital-interface
microphone solution.
The PCM4201 output data format is equivalent to the
Left-Justified data format supported by the DIT4096
transmitter. Although this format supports two channels for
stereo operation, the PCM4201 provides only one
channel, which corresponds to the left data channel of the
DIT4096 Left-Justified data format, and channel A of the
AES3 frame format. Figure 14 shows the physical
interface between the PCM4201 and the DIT4096
transmitter. The digital supply for the PCM4201 (V
DD
) and
the digital I/O supply for the DIT4096 (V
IO
) must be set to
the same voltage in order to ensure logic level
compatibility.

The PCM4201 is in Master mode, while the DIT4096 is in Slave mode.
Both operate from the same Master clock source.
The data format for the DIT4096 is configured for LeftJustified mode.
