Evaluation and Demonstration Boards and Kits provide a cost effective and easy to understand platform for evaluation, demonstration, reference design and applications development. PCM1865EVM is a flexible and multi-functional evaluation module based on digital audio interface receivers.

PCM1865EVM is suitable for developing and testing a wide range of digital audio interface products and solutions. The evaluation board includes a PCM1865 Digital Audio Interface Receiver, a high-efficiency AC-DC power supply (220V/110V) and related control/measurement/debugging accessories. It allows users to quickly evaluate PCM1865 or develop various digital receivers.

Application Field:

PCM1865EVM is suitable for developing and testing the digital audio interface products and applications. It is widely used in audio industry, such as automotive audio system, home entertainment, pro audio, public address systems, consumer-electronic products and other sound effects system. Furthermore, it can also be applied in the audio broadcasting and voice recognition.

Working Principle:

PCM1865EVM is based on PCM1865, a low-power, high-performance, multi-channel digital audio interface receiver. It supports up to 8 audio channels with 24-bit resolution for each channel at sample rates of 32kHz to 192kHz. The board provides a 6-pin header for easy interface with external monitoring equipment, as well as a series of signals for in-circuit measurement. This makes it a powerful tool for evaluating the performance of PCM1865.

When sound signal is inputted to the board, PCM1865\'s digital inputs receive the data and converts the signal into a digital stream, which is then transmitted to the digital audio outputs and played by the speaker. The board also provides control signal input and output capability. It can provide sample rate changes and mute control, and also includes measurement function for DC voltage, AC voltage, current, and other signal level measurements.

PCM1865EVM is designed with a high-efficiency AC-DC power supply (220V/110V), which ensures fast and stable power supply for the entire system. It also supports power save and sleep mode, enabling users to control power consumption. The board provides a series of ports and connectors such as I2C bus for control and monitoring function, as well as communication interfaces such as CAN, USB and RS-232 for control and communication.
