CS4328 18-Bit Stereo D/A Converter For Digital Audio

The CS4811 is a complete audio effects processing system integrated on a chip. This device features a proprietary 24-bit audio processing engine, substantial on-chip RAM, and a high-performance 24-bit audio codec. A serial control port enables the device to load firmware from a compact and cost-effective SPI or I2C serial EEPROM. Additional features, such as single +5 V operation, simplify system design. Firmware for the CS4811 is provided by Cirrus Logic, with two distinct firmware codes available: one for guitar effects and another for audio mixers. The guitar effects firmware offers a variety of electric guitar effects, including spring reverb, delay, chorus, flange, and tremolo. The mixer effects firmware includes a range of effects such as digital reverb, delay, and chorus, which are suitable for audio mixers, karaoke systems, and acoustic instrument amplifiers. The CDB4811GTR and CDB4811MXR evaluation boards facilitate the easy evaluation of the CS4811 device and its associated firmware, provided by Cirrus Logic, Inc.

The CS4811 audio effects processing system is a versatile solution designed for a wide range of audio applications. It incorporates a 24-bit audio processing engine, which ensures high fidelity and precision in audio manipulation. The integration of substantial on-chip RAM allows for efficient data handling and storage, enabling complex audio effects to be processed in real time without the need for external memory components.

The built-in high-performance 24-bit audio codec facilitates seamless audio input and output, ensuring that the processed audio maintains its quality throughout the signal chain. The device's ability to boot firmware from an SPI or I2C serial EEPROM allows for flexible firmware updates and customization, making it adaptable for various applications.

The device's single +5 V operation simplifies the overall system design, as it reduces the complexity of power supply requirements. This feature is particularly beneficial in portable or battery-operated devices, where power efficiency is crucial.

The dual firmware options enhance the CS4811's functionality, catering to both guitarists seeking rich effects and audio engineers working with mixers. The guitar effects firmware provides essential effects that enhance the electric guitar sound, making it suitable for live performances and studio recordings. On the other hand, the mixer effects firmware targets audio professionals looking to improve sound quality in mixers, karaoke setups, and acoustic instrument amplifiers.

The CDB4811GTR and CDB4811MXR evaluation boards serve as practical tools for developers and engineers to evaluate the performance and capabilities of the CS4811 device. These boards provide a platform for testing the various firmware options and understanding how the CS4811 can be integrated into different audio systems, facilitating the design and development of innovative audio solutions.The CS4811 is a complete Audio effects processing system on a chip.
