AS3422 EK-ST evaluation and demonstration board is a programmable evaluation board used for high signal-to-noise ratio (SNR) audio applications. It is ideal for developing and evaluating audio systems that need high SNR and performance. The board consists of four parts: the AS3422 Signal Core block, the AS3422 stereo receiver, the AS3422 output amplifier, and the audio codec.

The AS3422 signal core block is designed for high SNR audio applications with an 8-bit high SNR ADC and a wide dynamic range DAC for audio signal acquisition and playback, respectively. The core features an adjustable gain range from -20dB to +20dB, adjustable gain control for the input and output channels, and adjustable sample rate. It also includes an automatic gain control (AGC) and a built-in noise filter. The signal core block is connected to the ASIC stereo receiver, which can accept two input channels, a left and right channel.

The AS3422 stereo receiver includes the detection of the incoming signals and the reception of the received signals. It supports up to 8 analog microphone inputs and 4 direct digital microphone inputs. The receiver also supports the selection of the input channels from the multiplexed input channels and the automatic gain control (AGC). The receiver includes all the necessary functions to achieve a high SNR signal acquisition and it has been designed with the necessary logic and blocks for the implementation of digital signal processing algorithms for the different audio systems.

The AS3422 output amplifier includes the output of the received and processed signals using a stereo-balanced output, which is connected to the audio codec. This stereo output provides balanced high levels of SNR with good THD performance. The output amplifier has adjustable gain from -20dB to +20 dB and adjustable output impedance. The amplifier has adjustable gain control, polarity control, and mute control for both channels.

The audio codec provides an interface between the system and the output amplifier. It includes an 8-bit ADAC converter, which converts the analog signals into digital signals and it also includes a digital signal processor (DSP) for signal processing. The codec features an adjustable sample rate for different audio applications, adjustable thresholds for sensitivity and volume, adjustable data rate for output signal, and adjustable low-pass filter. The codec can also be used to control the volume level of the signal.

The AS3422 EK-ST evaluation and demonstration board can be used for developing high SNR audio systems. It consists of the AS3422 Signal Core block, the AS3422 stereo receiver, the AS3422 output amplifier, and the audio codec. The signal core block provides an adjustable gain range from -20dB to +20dB and the adjustable gain control for the input and output channels. The receiver provides the detection of the incoming signals and the reception of the received signals, while the output amplifier provides the stereo-balanced output. And finally, the audio codec provides the interface between the system and the output amplifier with its adjustable sample rate, adjustable thresholds for sensitivity and volume, adjustable data rate for output signal, and adjustable low-pass filter. With all these parts and features, the AS3422 EK-ST evaluation and demonstration board makes it ideal for developing and evaluating high SNR audio systems.
