AD1939YSTZRL application field and working principle

AD1939YSTZRL is a type of digital lossless media format codec and convertor. It is suitable for audio compressions and audio product conversions, especially for applications requiring high channel density and low total product cost. This article will discuss the application field and working principle of AD1939YSTZRL interface - CODECs, to provide readers with deeper understanding of the digital compressors.

Application Field

AD1939YSTZRL digital lossless media format codecs are ideally suited for audio compressions and audio product conversions. Their features include:

• Support a wide range of sampling frequencies including 8kHz, 22.05kHz, 44.1kHz, and 48kHz;
• Configurable latency;
• Configurable equalizer;
• Support AC-Coupled and ground-referenced line levels.

AD1939YSTZRL codecs can be used in many applications such as portable audio players, automotive audio systems, home theater systems, commercial audio systems, and professional recording systems.

Working Principle

AD1939YSTZRL codecs use a variety of audio compression algorithms to convert audio data from analog to digital format. Depending on the type of compression used, the codecs can reduce the size of an audio file by an average of about 35%. This size reduction allows more audio data to be stored and transmitted more quickly.

When an analog signal is converted to a digital signal, the data is first divided into discrete segments called samples. Each sample is converted to a digital value using pulse code modulation (PCM). PCM uses a fixed sample rate and bit depth (the number of bits used to represent the sample) to generate the digital signal. The samples are then encoded using the audio compression algorithm. Common audio compression algorithms used by the AD1939YSTZRL codecs include aptX, Dolby Digital, and DTS.

Once the audio has been compressed and encoded, it is decoded by the codec. The decoded signal is then converted from the digital domain to the analog domain using PCM, the sample rate and bit depth of the original digital signal being used. In this way, the original analog signal can be reconstructed and played back as intended.

AD1939YSTZRL codecs are a great way to reduce the size of audio files while still maintaining their sound quality. They are a cost-effective solution for audio product conversions and are highly suitable for applications where channel density and total product cost is important.
