Digital Signal Processors, or DSPs, are specialized microprocessors tailored to manipulate digital signals from analog input in order to achieve specific functions or results. One such DSP is the CS47L90-CWZR, a multi-channel stereo codec designed for a range of audio applications, from low-power, battery-operated desksets to active noise-cancelling headphones. This DSP is designed for high-resolution audio, featuring an on-chip 32kHz/48kHz sampling rate converter as well as integrated audio post-processing with zero-latency and low-power consumption.

The CS47L90-CWZR offers several key benefits over other available audio processing solutions. Its 32-bit Multi Signal Processor (MSP) architecture allows multiple functions to be performed on different audio streams at the same time. This gives manufacturers more flexibility when creating custom algorithms and signal processing applications. Additionally, its low power consumption is ideal for battery-operated designs, and it features low latency output and a wide dynamic range that provide premium audio fidelity.

The CS47L90-CWZR is ideal for many audio applications, including portable audio devices, gaming consoles, digital TVs, automotive infotainment systems, and wireless speakers. This device’s range of features includes high-resolution audio processing (up to 24-bit/192kHz streaming), seven-channel input / three-channel output (7in/3out) with independent mixing and pre-mastering, two low-noise preamps for analog microphone inputs, on-chip Digital Signal Processor (DSP) for audio post-processing with zero-latency, and four built-in high-efficiency DSP algorithms for voice processing and acoustic echo cancellation (AEC).

The basic working principle of the CS47L90-CWZR is as follows. Audio signals travel from the initial signal source, such as an analog microphone, and are then amplified using the device’s high-performance, low-noise preamps. The amplified signal is then sent to the Digital Signal Processor (DSP). The DSP processes the signal using its four built-in high-efficiency algorithms, which include multi-band bass control to shape the audio’s frequency response, noise reduction to reduce hiss and pops, and 3D audio processing to give the sound depth and realism. The processed signal is then sent to the stereo codec, which is used to convert the signal into a digital format that can be transmitted over any medium, such as USB, Wi-Fi, or Bluetooth.

The CS47L90-CWZR is an excellent choice for high-quality audio applications. Its combination of multitasking MSP architecture, low-noise preamps, low-latency output, and low-power consumption makes it an ideal option for a wide range of audio devices. Additionally, its four built-in high-efficiency algorithms provide enhanced audio post-processing for a better sound quality. With its ability to process multiple functions at the same time, manufacturers can create custom algorithms for their specific device needs, making the CS47L90-CWZR a powerful choice for audio applications.
