蓝牙汽车免提电话套件(HFCK)是数字信号处理模块，适用于引擎、风扇或其它噪音源带来的嘈杂的汽车环境。无线蓝牙标准可高度兼容并可轻松将移动电话集成到HFCK中。Blackfin®处理器可负荷高质量声学回声消除器AEC (VDA 类型 1)、噪音减弱、蓝牙协议栈、必要的用户档案及质量最好的语音文本识别功能。
Application Notes
AN-711: AD5227 Evaluation Kit for the 64-Position, Up/Down Control Digital Potentiometer (pdf, 898,361 bytes)
AN-588: AD7416/AD7417/AD7418 Power-On Reset Circuit (pdf, 30,326 bytes)
If a large number of decoupling capacitors are used on the VDD line, re-applying power before VDD has discharged to 0 V can cause the AD7416/AD7417/AD7418 to reset into an unknown. state.
