CS4245-CQZR is a widely used, high-performance multi-channel digital audio CODEC (Codec). It can be used for a number of applications, such as digital audio processing in automobiles and aircraft, professional home and studio recording, and machine listening and audio playback applications. It is easy to use, and has a number of highly efficient digital audio algorithms to ensure excellent sound quality. This article will discuss the application field and working principle of the CS4245-CQZR.

Application Field

The CS4245-CQZR is a digital audio CODEC capable of up to eight channels of audio input and output. It can be used in a wide range of applications, including automotive sound systems, home audio/video systems, aircraft audio systems, and professional recording studios. It can be used for real-time audio processing, such as equalization, dynamic range control, and noise-shaping. It can also be used to record and playback audio in high-fidelity formats such as DSD (Directly Stream Digital) and FLAC (Free Lossless Audio Codec).

In the automotive sound system, the CS4245-CQZR can provide excellent sound quality, due to its high-fidelity audio algorithms and low-latency performance. It can also be used in parallel with analog audio signals to provide a high degree of dynamic range and clarity. In aircraft audio systems, the CODEC can be used to provide high-fidelity sound reproduction, with minimal noise and distortion. In professional recording studios, the CODEC can be used to record high-fidelity audio with minimal noise and distortion.

In addition, the CODEC can be used for machine listening applications, such as speech recognition and sound localization. The CODEC’s digital algorithms can accurately detect and identify sounds in a wide array of environments. In audio playback applications, the CODEC can be used to accurately reproduce audio recordings in high-fidelity formats such as FLAC and DSD.

Working Principle

The CS4245-CQZR CODEC is composed of multiple components: a digital signal processor (DSP), a microcontroller, Flash memory, and a digital filter. The DSP is responsible for the audio processing tasks, such as de-noising, equalization, and dynamic range control. The microcontroller is used for communication between the DSP and the Flash memory, and for controlling the digital filter. The Flash memory is used for storing the DSP program and parameters, as well as for storing data from the audio inputs.

The CODEC also includes a digital filter, which is used for filtering out unwanted noise, such as white noise and harmonic distortion. The filter is capable of up to 20kHz of filtering, allowing for precise and accurate audio signal manipulation. The digital filter also features an adjustable phase and frequency response, allowing for fine-tuned audio performance.

The CS4245-CQZR CODEC is highly efficient, with excellent signal-to-noise ratio and low latency performance. It is capable of up to 24-bit/192-kilohertz audio resolution, with a THD+N (total harmonic distortion plus noise) of -100 dB. The CODEC also features a “Smart Power” feature that reduces the amount of energy used when the CODEC is in idle mode, improving efficiency and battery life.

In summary, the CS4245-CQZR is a highly efficient, multi-channel digital audio CODEC capable of up to eight channels of input and output. It can be used for a variety of applications, including automotive sound systems, aircraft audio systems, professional recording studios, and machine listening applications. The CODEC features a number of high-performance algorithms, including noise-shaping, dynamic range control, and digital filters. It is capable of up to 24-bit/192-kHz audio resolution, with a THD+N of -100 dB. The CODEC also features the “Smart Power” feature, which reduces the amount of energy used when the CODEC is in idle mode.
