2.2.2 AIC33 Interface
The EVM uses a Texas Instruments TLV320AIC33 stereo codec for input and output of
audio signals. The codec samples analog signals on the microphone or line inputs and
converts them into digital data so it can be processed by the DSP. When the DSP is
finished with the data it uses the codec to convert the samples back into analog signals
on the line output so the user can hear the output.
The codec communicates using two serial channels, one to control the codec’s internal
configuration registers and one to send and receive digital audio samples. The I 2 C bus
is used as the AIC33’s control channel. The control channel is generally only used
when configuring the codec, it is typically idle when audio data is being transmitted,
McBSP1 is used as the bi-directional data channel. All audio data flows through the
data channel. Many data formats are supported based on the three variables of
sample width, clock signal source and serial data format. The EVM examples generally
use a 16-bit sample width with the codec in master mode so it generates the frame
sync and bit clocks at the correct sample rate without effort on the DSP side.
The codec is clocked via a 27 Mhz oscillator. The internal sample rate generator
subdivides the default system clock to generate common audio frequencies. The
sample rate is set by a codec register. The figure below shows the codec interface on
the DM355 EVM.
