Texas Instruments AFE7070 / AFE7071双通道14位数模转换器
德州仪器 AFE7070和AFE7071是双通道14位65MSPS数模转换器,具有集成的可编程四阶基带滤波器和模拟正交调制器。TI AFE7071包括附加数字信号处理特性,例如具有本地震荡(LO)和边带抑制功能的正交调制器校正电路等。AFE7070将一个直接数字合成器(DDS)与32位数控振荡器(NCO)和LVDS输出缓冲器组合在一起。 该器件适用于低功耗、紧凑型软件无线电和家庭基站(Femto)及微微蜂窝基站收发信机(Pico-Cell BTS)。有评估模块可测试AFE7070和AFE7071的性能。特性
