description

The TLV320AIC22 is a dual coder/decoder (codec) for voice applications, including voice-over-internet protocol

(VOIP). It features two ADC conversion channels and two DAC conversion channels that can be connected to

a handset, headset, speaker, microphone, or a subscriber line via an analog crosspoint.

The TLV320AIC22 has a flexible serial interface that allows the two channels of the TLV320AIC22 to be

interfaced to a single multichannel buffered serial port (McBSP) of the DSP. The two channels share the digital

interface at different time slots. Up to four TLV320AIC22 units can be cascaded together to allow eight channels.

For control purposes, either the serial interface or the I C interface can be used. Programmable gain amplifiers,

preamplifier gain, microphone bias voltages, and analog crosspoint are programmed through the serial

interface or the I C interface. The TLV320AIC22 can be powered down, via a dedicated pin or by using software

control, to reduce power dissipation.
