Audio Special Purpose applies to numerous technology solutions, including the CS8421-EZZ. The CS8421-EZZ is an integrated digital audio receiver and sample rate converter providing integration of consumer audio and professional audio interface formats. The CS8421-EZZ provides a low-cost, cost-effective solution for consumer audio to professional audio interface and for sources including consumer audio/video components, sonar, and audio/video conferencing.
The CS8421-EZZ is designed to improve audio fidelity by bridging consumer audio and professional audio interface formats, allowing signals to be transmitted in their respective formats. The CS8421-EZZ supports both consumer-level and professional audio formats by accepting a digital audio signal from a consumer audio source and providing a digital audio signal to a professional audio format, or vice versa. This allows for seamless integration between consumer audio and professional audio interfaces.
The CS8421-EZZ is equipped with a 32-bit floating-point mixed-signal conversion engine to ensure high-performance, low-power operation. This conversion engine is capable of supporting sampling frequencies up to 48 kHz and sample rates up to 192 kHz. The CS8421-EZZ includes built-in sample rate conversion (SRC) to maintain a constant output frequency despite variations in the input frequency and sample rate. This allows the CS8421-EZZ to adapt to a wide range of consumer audio and professional audio applications, increasing flexibility and saving costs.
The CS8421-EZZ supports several consumer audio and digital interface formats, including S/PDIF (AES3), consumer digital optical, consumer AES3, and low-voltage differential signaling (LVDS). The CS8421-EZZ also supports professional audio formats such as AES/EBU, analog FM, S/PDIF (AES3), and the I2S interfaces. In addition, the CS8421-EZZ supports data formats such as DSD, DTS, and AC3.
The CS8421-EZZ includes a range of features to ensure optimal performance. The built-in sample rate converters ensure seamless conversion of audio signals from consumer to professional levels, eliminating the necessity of converting signals outside of the device. Additionally, the CS8421-EZZ includes a built-in digital de-emphasis circuit to ensure optimal audio playback, and features an adjustable low-pass filter for improved signal-to-noise ratio. The adjustable filters also allow for tailored frequency response for different applications, ensuring the CS8421-EZZ is adaptable to various audio playback requirements.
The CS8421-EZZ also includes a range of industry-leading features to ensure efficient operation. The device provides simultaneous digital audio clocking, eliminating the need for manual synchronization. Additionally, the CS8421-EZZ can be configured to synchronize to incoming signals, providing support for both master-to-slave and inter-component synchronization. The CS8421-EZZ also includes a sophisticated signal-processing engine to ensure optimum audio performance.
In summary, the CS8421-EZZ is a versatile and cost-effective integrated digital audio receiver and sample rate converter solution for integrating consumer audio and professional audio interface formats. The device can be configured to support a wide range of audio formats, and its built-in features ensure optimal performance and efficiency. With its combination of features, the CS8421-EZZ is an ideal solution for applications in the Audio Special Purpose market.
