SWCS032 – OCTOBER 2008
The audio codec in the device includes five DACs and two ADCs to provide multiple voice channels and
stereo downlink channels that can support all standard audio sample rates through I2S/TDM format
interfaces. The audio output stages on the device include stereo headset amplifiers, two integrated
class-D amplifiers providing stereo differential outputs, predrivers for line outputs, and an earpiece
amplifier. The input audio stages include three differential microphone inputs, stereo line inputs, and
interface for digital micrphones. Automatic and programmable gain control is available with all necessary
digital filtering, side-tone functions, and pop-noise reduction.
