Product Overview

The TLV320AIC22CPT is a Two Coder/Decoder (Codecs) for voice applications, including voice over internet protocol (VoIP). It features two analogue-to-digital converter (ADC) channels and two digital-to-analogue converter (DAC) channels that can be connected to a handset, headset, speaker, microphone or a subscriber line via an analogue cross-point. 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 to four TLV320AIC22C units can be cascaded together to obtain eight channels. For control purposes, either the serial interface or the inter-integrated circuit (I²C) interface can be used. Programmable-gain amplifiers (PGAs), preamp gain, microphone bias voltages and analogue cross-point are programmed through the serial interface or the I²C interface.
