356835-1 is a small-sized, robust, single-chip PCM codec IC with embedded ROM that provides multi-language support and acoustic echo cancellation (AEC) and noise suppression (NS). It was developed based on Texas Instruments\' high performing Direct Digital Conversion (DDC) architecture. This IC achieves superior performance compared to conventional analog codecs, and fully implements the functional interface and control requirements of existing applications.

356835-1 is mainly used in multimedia products, such as gaming and home theater systems, video conferencing, and IP phones. It can be used in various applications with its low power consumption rate, extended temperature range, and low RMS noise. Also, the device\'s acoustic echo cancellation and noise suppression functions are superior to conventional analog codecs.

356835-1\'s working principle is Direct Digital Conversion (DDC). Instead of relying on analog-to-digital conversion to process sound, DDC works by converting analog signals into digital signals. This allows for a more accurate representation of sound that is free from distortion. The device also features an onboard Digital Signal Processor (DSP) that provides its AEC and NS functions. DSPs are general-purpose processors that can be programmed to handle various tasks, such as signal analysis and audio processing. In the case of the 356835-1, the incorporated DSP is programmed to process incoming acoustic signals and reduce background noise.

The main advantage of using 356835-1 is its low power consumption rate. The device is designed for no-idle operation, which means that it only consumes power when it is active. This significantly reduces the power consumption of the system, ensuring that the device is energy-efficient. Additionally, the 356835-1 is a single-chip solution with its internal ROM, which eliminates the need for external memories.

Overall, the 356835-1 is a high-performance codec that offers an optimal combination of energy efficiency and acoustic accuracy. The device is well suited for applications that require robust performance in a small form factor. It is a cost-effective solution that is designed to meet the needs of a wide range of multimedia products, including gaming and home theater systems, video conferencing, and IP phones.
