摘要:
 在分析Purepath无线音频协议的基础上,设计了基于CC8531的高保真、低功耗的USB无线声卡。结合系统需求拟定了以CC8531无线音频流芯片为核心、TLV320AIC3254为音频解码器、辅以按键控制和LDO电源降压电路等外围模块的硬件结构,并分析了各个模块的电路设计。在此基础上,通过使用Purepath无线配置平台对CC8531芯片进行参数配置和固件烧写,实现了完整的系统。经过测试,USB无线声卡能稳定传输CD级高保真音质,距离最高达到130 m,并实现了条件配对组网、自动功耗调节、远程音量控制等功能,可用于板载声卡的替代,也可用作无线耳机、无线音响,具有一定的市场价值。
Abstract:
 Based on the analysis of Purepath wireless audio protocol,a CD-class low-power USB wireless soundcard is designed. Combi-ning the system requirements,a system structure is developed based on RF streaming chip CC8531,the codec TLV320AIC3254 and other peripheral function modules. Then a detailed description of the circuit design is given. After that,CC8531 chip is programmed through the Purepath wireless platform and a complete system is finally finished. As test shows the USB wireless soundcard can achieve a high-fideli-ty wireless transmission with distance up to 130 m. In addition,the system increases pairing networking,automatic power adjustment,vol-ume control and other functions. It can not only used as an alternative to onboard soundcard but also as a wireless headset or a wireless au-dio speaker.
