基于MSP430F5438A的AD9854驱动，AD9854的DDS核具有48位的频率分辨率（在300M系统时钟下，频率分辨率可达1uHZ）。输出17位相位截断保证了良好的无杂散动态范围指标。AD9854允许输出的信号频率高达150MHZ(Based on the AD9854 driver of MSP430F5438A, the DDS core of AD9854 has a frequency resolution of 48 bits (up to uHZ at 300 M system clock). Output 17-bit phase truncation ensures a good dynamic range index without spurious. AD9854 permits up to 150 MHZ of output signal frequency)
