Description

The TLC320AD90C is designed to be 100% compliant with the audio codec \x9197 (AC\x9197) standard specification. The codec is designed to be controlled by a digital controller. The two fixed 48-kHz sample rate DACs support a stereo PCM output channel that contains a mix, determined by the codec controller, of all digital audio sources, including an internal synthesizer, and any other digital sources. The output of these DACs is mixed with additional analog sources and sent to the independently controlled LINE_OUT output. For a speakerphone, the MONO_OUT output delivers either mic only or a mono mix of sources to a telephony subsystem. The ADC path supports two channels of fixed 48-kHz sample rate inputs.
