The AD9119-MIX-EBZ is an evaluation board for a Digital-to-Analog Converter (DAC). It features an integrated software interface to easily setup, monitor, and control the evaluation board. The AD9119-MIX-EBZ evaluation board contains an Intermediate Frequency (IF) signal chain with a high-speed DAC, along with a driver amplifier with an output mixer.

The AD9119-MIX-EBZ supports audio/video (AV), broadcast, and consumer applications, such as transmitters, radios, smart home solutions, digitalstill cameras, video conferencing systems, digital studio processing systems, and many others. It is designed for both the industrial and commercial markets, to offer high-performance, reproducible solutions to common analog-to-digital signal conversion requirements.

Principle of Operation

The AD9119-MIX-EBZ evaluation board consists of an intermediate frequency (IF) signal chain with a high-speed DAC and a driver amplifier with an output mixer. The IF signal chain includes a variable gain amplifier (VGA), an automatic gain control (AGC) circuit, and a 12-bit voltage-output DAC. The digital output of the DAC is converted to an analog signal by the VGA and amplified by the driver amplifier. The mixer then converts the amplified IF signal to a frequency-shifted IF signal, enabling the evaluation board to be used in applications such as frequency-division multiplexing.

Features and Benefits

The AD9119-MIX-EBZ offers several features that make it the optimal solution for AV, wireless, and consumer applications. It is designed with an integrated software interface that facilitates setup, monitoring, and control of the evaluation board. The AD9119-MIX-EBZ supports a variety of input formats, including two-channel stereo, single-channel mono, and dual-channel mono. The evaluation board also has a wide bandwidth, which enables it to process audio signals at rates up to 32 kHz.

The AD9119-MIX-EBZ is equipped with a high-performance mixer, featuring a low noise floor of -88 dBc/Hz. The mixer is designed to minimize spurious outputs, allowing for high-fidelity sound reproduction. The AD9119-MIX-EBZ also offers several protection features, including overload protection, EMC protection, and short-circuit protection. These protection features ensure reliable operation in harsh industrial environments.

Conclusion

The AD9119-MIX-EBZ evaluation board is an ideal solution for AV, broadcast, and consumer applications. The evaluation board features an integrated software interface for easy setup, monitoring, and control. It also offers several features and benefits, including a high-performance mixer, wide bandwidth, protection features, and more. The AD9119-MIX-EBZ is designed to provide reproducible solutions to signal conversion requirements in the industrial and commercial markets.
