Evaluation and Demonstration Boards and Kits encompass a variety of tools essential for the evaluation, development, and demonstration of both commercial and automotive infotainment systems. XK-USB-AUDIO-HPA from XK Electronics is an excellent example of such a device in this area.Built on an Altera Cyclone V SE, the XK-USB-AUDIO-HPA includes two AD1939 audio controllers and two TAS1310 digital audio processing chips. This allows it to support USB audio functions such as digital-to-analog/analog-to-digital conversion, as well as the generation and distribution of audio signals via the TAS1310s. It also supports up to 24 simultaneous audio channels and is fully compatible with multiple audio-related standards, such as USB Audio Class 1.0 and HDMI-CEC.XK-USB-AUDIO-HPA can be used for a variety of applications in the infotainment domain. Its advanced audio processing capabilities can be employed to reproduce high-quality audio from multiple sources, including digital and analog inputs. It is also capable of providing an array of audio processing function blocks, such as equalization, volume control, and tone control. Additionally, its signal-processing capabilities are further enhanced by support for up to 24 simultaneous audio channels. Beyond infotainment systems, XK-USB-AUDIO-HPA is also a versatile solution for industrial automation. It can be used to interface with numerous industrial-grade sensors, such as accelerometers, temperature sensors, and pressure sensors. Its real-time implementation of audio distribution allows industrial systems to generate high-quality audio from multiple sources without needing to install dedicated speakers for each source.The working principle of the XK-USB-AUDIO-HPA demonstrator board is as follows:The on-board Audio Codec communicates with the PC via the USB 2.0 interface and receives commands on the Audio Codec\'s I2C protocol. It then transmits these commands to the Audio Driver which passes the commands over to the TAS1310s for audio processing. The TAS1310s implementation then acts upon these commands in real-time, modifying the audio signals accordingly. The Digital Audio Converters (DACs) and ADC then processes the modified signals for conversion to and from analog and digital formats, respectively. Finally, these signals are then routed back to the Audio Codec in real-time for the final output.In short, XK-USB-AUDIO-HPA is an incredibly powerful and versatile tool for automotive infotainment and industrial automation applications. Its extensive functionality, range of supported standards, support for multiple audio channels, and real-time audio processing capabilities allow it to be employed for a wide variety of tasks related to audio playback, signal distribution, and control.
