The CS42426-DQZ is a stereo audio Codec that uses delta-sigma modulation principles to produce high-quality audio in a cost-effective, low-power package. The device has dual-channel inputs, dual-channel outputs, and supports a wide range of sample/bit rate combinations, including 16/20/24-bit recording/playback and 44.1 kHz, 48 kHz, and 96 kHz sample rates. The device features a high-end filter bank with adjustable filter parameters that enable precise adjustment of frequency response and system configurations. The CS42426-DQZ also includes a fully-configurable, one-stop clocking architecture that eliminates the need for external clock buffers or external clock sources.

The CS42426-DQZ is designed for use in a range of applications in the audio/multimedia market, from home theater systems to automotive audio systems. In particular, it is an ideal solution for professional audio production, such as sound reinforcement, post-production, and broadcast applications. Additionally, the CS42426-DQZ can be used in consumer audio systems, gaming systems, and embedded applications that require high-quality audio.

The working principle of the CS42426-DQZ begins with the two-channel input signal, which is first processed through a pre-filtering stage to reduce any external noise and interference. This is followed by a delta-sigma modulator and Digital Signal Processor, which encodes the input signal into a digital audio stream. This digital audio stream is then encoded using the device\'s encoder and stored in a memory, from which it is retrieved by the device\'s decoder. The output from the decoder is then passed through a post-filter for further noise reduction before being outputted as two channels of high-quality analog audio.

The CS42426-DQZ also includes several features and options to ensure the highest quality audio reproduction possible. The device includes a single-layer clocking architecture that enables precise timing control of the digital audio stream. It also features a low latency and Jitter filter to ensure the cleanest digital audio stream possible. Additionally, the device includes several post-processing features, such as adjustable EQ, dynamic range control, and a customizable limiter, to ensure that the highest possible fidelity is achieved in digital audio systems.

The CS42426-DQZ is an ideal solution for a wide range of audio applications that require high-quality, low-power audio reproduction. Its delta-sigma modulation architecture ensures the highest possible fidelity, while its ease-of-use, configurability, and low-power consumption make it an ideal choice for applications where space, power, and cost are of the utmost importance.
