PCM2903E/2KG4 is a monolithic CMOS digital audio signal processor for stereo digital audio playback and record applications. It integrates a stereo digital-to-analog converter (DAC) and an analog-to-digital converter (ADC) for converting digital audio signals to and from analog signals. It can also be used as a stereo A/D sound up-sampler, a digital interface transducer, and a digital multi-channel audio processor.

The PCM2903E/2KG4 is a multiplexed dual-channel 24-bit CODEC that supports stereo playback and recording up to 24-bit/96 kHz sample rate. It implements advanced audio signal processing algorithms to provide superior SNR performance and low distortion as well as a narrow response profile. It also includes a low-noise analog pre-amplifier and a 24-bit audio DAC/ADC with programmable sampling rate.

The PCM2903E/2KG4 is designed to be employed in digital playback applications, such as mobile phones and portable media players. It can decode digital audio streams from multiple sources such as compact discs, digital audio tapes (DAT), MPEG audio files, and other compressed audio formats. It can also generate digital audio signals for playback to digital audio destinations, such as loudspeakers, headphones, or digital audio systems.

The PCM2903E/2KG4 enables direct digital sound up-sampling, digital signal routing, and sample-rate conversion as well as high-level signal processing for audio applications. In addition, it features a range of programmable input and output formats, including I2C or SPI bus interfaces, and support for a variety of clock and control signals.

The PCM2903E/2KG4 is based on a single-chip architecture and it provides low-power operation and low latency. Its efficient signal processing capabilities ensure that it performs in a wide range of demanding, high-quality audio applications. With its easy-to-use design and low-power performance, it is suitable for a variety of applications.

The PCM2903E/2KG4 works by converting analog signal elements into digital signal elements according to predetermined digital format. The digital signal is then routed through high-level digital signal processing techniques, such as a low-pass filter, digital signal routing, sample-rate conversion, and direct digital sound up-sampling. The engine then sends the processed digital signal to an output device such as a loudspeaker or digital cable. The engine also supports input and output control signals, including I2C or SPI bus interfaces.

In summary, the PCM2903E/2KG4 is a monolithic CMOS digital audio signal processor for stereo digital audio playback and record applications. It is based on a single-chip architecture and features a compact design for low power operation and low latency. It provides a range of programmable input and output formats and supports a variety of clock and control signals. It also implements advanced audio signal processing algorithms to provide superior SNR performance and low distortion as well as a narrow response profile. The PCM2903E/2KG4 is designed for use in digital playback applications, such as mobile phones and portable media players, and can be employed for direct digital sound up-sampling, digital signal routing, and sample-rate conversion.
