The CS42L51-CNZR is an Analog to Digital / Digital to Analog Converter (ADC / DAC) chip, which is an important component of audio experience. It is designed for applications such as mobile phones and portable media, and it contains a built-in low pass filter for audio fidelity. In this article, we will introduce the application field and working principle of the CS42L51-CNZR, which belong to the “interface-codecs” classification.

One of the main applications for the CS42L51-CNZR is for portable media, such as mobile phones, MP3 players and other audio players. CS42L51-CNZR has the perfect combination of features to meet the needs of portable media, such as low power consumption, wide dynamic range and compact package size. With the help of CS42L51-CNZR, audio players can improve the sound quality by reducing power consumption and delivering better output.

In mobile phones, CS42L51-CNZR can be used for voice communication and multimedia recording. The built-in low pass filter in the chip allows improved audio fidelity and reduced background noise. It also supports a wide range of input and output formats, including MP3, AAC, and WAV. The CS42L51-CNZR can provide excellent sound quality for voice communication, music playback and recording.

In addition, CS42L51-CNZR is compatible with a wide variety of digital audio interfaces, including I²S, DSD and TDM.The chip supports up to 8-channel stereo for high fidelity audio performance and up to two independent stereo ADC and DAC channels respectively with low power consumption.

The CS42L51-CNZR also supports “multi-bit” mode, which combines two 16-bit channels into one 32-bit channel with improved dynamic range and reduced crosstalk. This allows for improved sound quality for low-level signals. This feature also allows for compatibility with multiple audio formats.

The working principle of the CS42L51-CNZR is based on an architecture that uses an analog-to-digital (A/D) converter, a digital-to-analog (D/A) converter and an integrated filter. The A/D and D/A converters respectively convert analog audio signals into digital signals and vice versa. The integrated filter filters out unwanted high-frequency noise for improved sound quality.

The A/D converter receives analog audio signals and converts them into digital signals. The digital signals are then sent to the D/A converter, which converts them back into analog audio signals. The integrated filter then filters out high-frequency noise to produce clean and crisp sound with improved audio fidelity.

In addition, the CS42L51-CNZR is also equipped with many other features such as an internal programmable clock, multiple input/output formats, sample rate conversion and low power consumption. To increase the accuracy of the output signals, the chip also contains various built-in special features, such as a differential output stage.

To summarize, the CS42L51-CNZR is designed for high fidelity audio applications in portable media such as mobile phones and audio players. The chip is also compatible with a wide variety of digital audio formats, provides low power consumption and offers high-quality current-mode output stages. It also has a built-in low pass filter for improved audio fidelity and lower crosstalk. The architecture of the chip is based on the use of an A/D converter, a D/A converter and an integrated filter.
