The PCM2900CEVM-U is designed for use in the field of evaluation and demonstration boards and kits for audio connectivity. It is an audio codec module capable of both encoding and decoding audio data streams. The codec offers features such as low latency, programmable sample rate, and support for various audio data formats. The kit includes the necessary hardware and software components to perform an evaluation of the codec’s features and the accuracy of its audio decoding and encoding processes.

The PCM2900CEVM-U module is based on the PCM2900C audio codec. This audio codec chip supports both high-resolution audio and low-bandwidth audio formats, and can be used for applications ranging from portable audio players to car stereo systems. The module supports many of the same features as the PCM2900C, including a wide sample rate range, selectable sample rate, selectable channel configuration, low latency, and low power consumption. It also provides audio support for multiple operating systems, including Windows, iOS, and Android.

The working principle of the PCM2900CEVM-U is simple and straightforward. The module takes an audio analog signal as an input and then converts it into a digital signal. It then uses its onboard digital-to-analog stimulator (DAS) and digital signal processor (DSP) to process and encode the audio signal. The encoded digital signal is then passed through a bank of filters to remove any unwanted noise and improve signal clarity. The output signal can then be decoded back to the original analog signal for playback.

Once the PCM2900CEVM-U module is connected to a computer, users can use the included software to determine the module’s audio performance. The software can also be configured to apply various effects and modify settings for better audio quality. The device also includes several audio connectors which can be used to connect to external speakers or headphones for playback of the encoded audio signal.

In addition to its audio performance evaluation functions, the PCM2900CEVM-U module can also be used as a testing platform for audio designs. By connecting the module to a custom-built audio system, developers can test various audio-related implementations, such as custom filters, crossovers, and distortion correction. This makes the PCM2900CEVM-U an ideal tool for developers who want to quickly prototype and evaluate audio systems.

Overall, the PCM2900CEVM-U module is a versatile and powerful tool for evaluating audio performance. Not only does it offer completely programmable control over the sample rate, channel configuration, and audio processing effects, but it can also be used to evaluate a variety of audio design projects. With its easy-to-use software and comprehensive support for multiple operating systems, the PCM2900CEVM-U is an excellent choice for those looking to evaluate and develop audio systems.
