This article will provide an overview of the TLV320AIC1110GQER application field and working principle.

TLV320AIC1110GQER Application Field

The TLV320AIC1110GQER is mainly used in communication applications such as VoIP and VoLTE, but it can also be used in a variety of other applications including audio processing and professional recording. The device is a low-power and low-distortion codec with a wide dynamic range, which makes it a great choice for applications requiring high-quality sound. It also supports a wide range of sample rates and hosts, making it suitable for applications in various industries.

Additionally, the TLV320AIC1110GQER is an integrated CODEC featuring a wide range of digital and analog I/O, including programmable input, analog loopback and digital MSBs, which makes it suitable for applications requiring multiple audio sources, such as sound reinforcement and multi-room audio systems. The device also features a low-latency digital audio processor and a wide range of integrated digital filtering capabilities to provide superior sound quality.

TLV320AIC1110GQER Working Principle

The TLV320AIC1110GQER is an integrated CODEC featuring two converters – an analog-to-digital (ADC) and a digital-to-analog (DAC) converter. It also includes a low-latency digital audio processor, and a wide range of integrated digital filtering capabilities.

The ADC and DAC converters process incoming and outgoing audio signals. Both datapaths can be optimized individually by selecting different sample rates, audio data widths, and data protocol selection. The data I/O is managed by the MCLK (Master Clock), which can be a Clock Reference Crystal Oscillator (CRYSTO) or a PLL/VCO (Phase Locked Loop/Voltage Control Oscillator). The CRYSTO is a low-cost, high-performance clock reference that is used for the system synchronous clock.

The digital audio processor handles all digital audio processing, such as sample rate conversion, noise-shaping and pre- and post-processing digital filters. This processor is controlled by the host\'s I2C bus. The user can also control the audio processing via the digital I/O (DIO) lines.

The TLV320AIC1110GQER also includes several analog features, such as adjustable bias voltage for microphone bias, programmable analog loopbacks for AEC (Acoustic Echo Cancellation) and clear-channel detection, as well as programmable analog gain and active-ground noise filters for improved signal-to-noise ratio. The device also features a wide range of analog I/O, including mic and line input, headphone out, and line out.

Conclusion

The TLV320AIC1110GQER is an integrated CODEC designed for use in communication applications such as VoIP and VoLTE. It integrates two converters, a low-latency digital audio processor, and a wide range of integrated digital filtering capabilities to provide superior sound quality. It also includes several analog features, such as adjustable bias voltage for microphone bias, programmable loopback and active-ground noise filters, to support a variety of audio application requirements. With its wide range of digital and analog I/O, the TLV320AIC1110GQER is the ideal choice for communication applications.
