Key Features

  • two analog-to-digital converter (ADC) channels and two digital-to-analog converter (DAC) channels that can be connected to a handset, headset, speaker, microphone, or a subscriber line via an analog crosspoint. The TLV320AIC22C has a flexible serial interface that allows the two channels of the TLV320AIC22C to be interfaced to a single multichannel buffered serial port (McBSP) of the external digital signal processor (DSP). The two channels share the digital interface at different time slots. Up.
