5.5.10 Digital Mixing and Routing
The TLV320DAC3101 has four digital mixing blocks. Each mixer can provide either mixing or multiplexing
of the digital audio data. This arrangement of digital mixers allows independent volume control for both the
playback data and the key-click sound. The first set of mixers can be used to make monaural signals from
left and right audio data, or they can even be used to swap channels to the DAC. This function is
accomplished by selecting left audio data for the right DAC input, and right data for the left DAC input. The
second set of mixers provides mixing of the audio data stream and the key-click sound. The digital routing
can be configured by writing to page 0 / register 63, bits D5–D4 for the left channel and bits D3–D2 for the
right channel.
Because the key-click function uses the digital signal-processing block, the CODEC_CLKIN, DAC, analog
volume control, and output driver must be powered on for the key-click sound to occur.
