The PCM2900EG4 is an integrated high performance device for low power applications. It is an interface CODEC that includes a USB transceiver, a stereo high-performance sound stream controller, and a microphone preamp with balanced and unbalanced inputs. With its low power consumption, and its small footprint, the PCM2900EG4 is perfect for portable applications.PCM2900EG4’s main application field is digital audio processing: it is designed to provide high quality audio conversion, recording and playback on computers, mobile phones, surveillance and audio equipment, speakers and drones, etc. The device is suitable for applications that require low power consumption, low latency transfers and low noise levels.The PCM2900EG4 also supports: 16 or 24 bit formats and sampling rates of 8, 16, or 24 kHz, controls through stand-alone Microcontroller, steaming, over-sampling and pre-processing, audio path and signal processing, conversion and digital mixers, analog and digital audio effects, and local audio. The PCM2900EG4 is based on the following working principles:1) USB Interface: The device includes a USB signal processor and a USB transceiver, which provide USB signal communication between the host and the device. It is compatible with USB 2.0 and 3.0, so it can provide fast data transfer and low-latency communication with other USB-enabled devices. 2) Stereo Sound Stream Controller: The device includes a stereo sound stream controller, which is capable of handling up to 48 channels of input and output for stereo audio. The controller provides sound signal processing, such as mixing, summing, attenuation, and soft clipping. 3) Microphone Preamp: The PCM2900EG4 includes a microphone preamp with two balanced and two unbalanced inputs. This allows the device to optimize mic recordings, reduce noise and enable controlled signal levels. 4) Digital Signal Processing: The device can perform audio signal processing on both the analog and digital audio signals. It supports 48 kHz sample rate and 16 bit or 24 bit format. It can also perform A/D and D/A conversion for digital audio by using a dedicated digital signal processor. 5) Audio Effects: The PCM2900EG4 can apply a range of audio effects, such as 3D sound, reverberation and echo, noise reduction, dynamic range compression, and Hi-Fi sound effects. The PCM2900EG4 is a highly integrated high performance device designed to enable low power applications, such as in mobile phones, surveillance and audio equipment, and speakers. It features a USB transceiver, a stereo sound stream controller, and a microphone preamp with balanced and unbalanced inputs. The device supports a range of audio formats and sample rates, and is capable of performing a variety of operations, including streaming, over-sampling, pre-processing, and audio signal processing. It can also apply various audio effects to the audio signals for improved sound quality.
