Audio CODEC Interface

The audio CODEC TLV320AIC3206 is a flexible, low power, low-voltage stereo audio CODEC with
programmable input and outputs, PowerTune capabilities, fixed predefined and parameterizable signal
processing blocks, integrated PLL, and flexible digital interfaces.
This audio CODEC is interfaced to the I2S2 port and I2C bus of the C5545. Audio line in and line out
connections are provided through 3.5 mm audio jacks. An on-board microphone CMC-2242PBLA from
CUI is provided for audio recording.
NOTE: When the AIC3206 CODEC is not powered (when the C5545 BoosterPack is not powered),
a potential for crosstalk between Line In and Stereo Out exists, resulting in distorted audio
from Line In to Stereo Out when a high amplitude signal present on Line in.
