1 GSPS正交数字上变频器，内置18位IQ数据路径和14位DAC

AD9957可用作通用I/Q调制器与捷变上变频器，适合视成本、尺寸、功耗和动态性能为关键因素的通信系统。它在单芯片上集成了一个高速直接数字频率合成器(DDS)、一个高性能、高速14位数模转换器(DAC)、时钟乘法器电路、数字滤波器以及其它DSP功能，为有线或无线通信系统中的数据传输提供基带上变频。\n\n AD9957是正交数字上变频器(QDUC)系列中的第三款器件，另外两款器件是AD9857和AD9856。它的工作速度、功耗和频谱性能均有所提升。与前两款产品不同，它支持可用于I/Q基带数据的16位串行输入模式。或者，也可以对这款器件进行编程，用作单音正弦源或插值DAC。 \n\n • 1 GSPS内部时钟速度（高达 400 MHz模拟输出）\n\n• 集成1 GSPS、14位DAC\n\n• 输入数据速率：250 MSPS\n\n• 相位噪声 ≤ −125 dBc/Hz（1 kHz偏移，400 MHz载波）\n\n• 卓越的动态性能：>80 dB 窄带 SFDR\n\n• 8个可编程配置文件，支持移位键控\n\n• Sin(x)/(x)校正（反正弦滤波器）\n\n• 参考时钟倍频器\n\n• 内部振荡器，支持单晶体操作;
