The PCM4202EVM, analog to digital converter (ADC) evaluation board, is designed for monitoring and evaluation of performance of the Marvell PCM4202 analog to digital converter. The board is designed to utilize both the performance and flexibility of its features to suit a variety of application scenarios in the field of audio, automotive, industrial, and medical markets.

The PCM4202EVM has been constructed with the PCM4202 audio Codec and a complete suite of digital and analog audio interface components. The Codec serves as the primary analog to digital (A/D) interface, driving and receiving audio signals in differential line-level format from input devices. Leveraging the power of a 28-bit A/D converter, the board is able to capture audio with a low distortion level and high signal-to-noise ratio (SNR). When connected to a PC through a USB port, the PCM4202EVM enables high-quality audio recording and playback.

The evaluation board is equipped with a range of features, including single-ended and differential input selections and gain controls. The board also features adjustable gain and bass boost controls, a variable bass roll-off, and a high-resolution digital audio output in the I2S format. External circuitry such as a headphone amplifier, a low-pass filter, or an active filter can be connected to the output of the board for enhanced audio performance.

At the heart of the PCM4202EVM is the PCM4202 audio Codec, a 28-bit A/D converter, from Marvell. The Codec offers unprecedented performance in terms of signal-to-noise ratio (SNR) and distortion. Two integrated temperature sensors enable real-time temperature monitoring of the board. In addition, the Codec features sigma-delta modulation, noise shaping, and multi-bit noise shaping technology, which ensures superior audio performance with a minimal number of components.

The evaluation board also features a range of software support, including Windows-based software and drivers for easy setup and evaluation. Additionally, the board includes pre-defined commands for controlling the PCM4202EVM from the PC\'s command line.

The PCM4202EVM offers several advanced features designed to ensure improved performance. These features include line-rate monitoring and control, SNR improvement, and multi-bit noise shaping. The board also offers sample rate conversion and dynamic range control to ensure optimal audio performance. In addition, the board includes advanced equalization circuitry for CD-quality audio reproduction, and audio compression features for dynamic range control.

The PCM4202EVM is an ideal solution for any application that requires high-quality audio recording and playback. The board\'s integrated temperature sensors, adjustable gain and bass boost controls, and advanced digital signal processing features makes it ideal for audio applications in medical, automotive, and industrial markets. In addition, the board\'s comprehensive software package and pre-defined commands make it easy to configure the board for a variety of applications.
