Abstract在GPS驯服时钟中,需要将CPU计算所得的控制数字量使用D/A转换器转化为对应的模拟电压,从而实现对VCOCXO的输出频率进行校正,数模转换的精度直接影响振荡频率的控制精度.本文给出了DAC1220数模转换器的工作原理和特点以及其使用方法,并探讨了D/A转换器分辨率与控制晶体时钟频率之间的关系.; GPS disciplined clock system,in order to calibrated the frequency of VCOCXO,It is necessary to transfer control digital calculated by CPU to corresponding anolog voltage.the paper discussed the principle and application of DACl220 converter,and expatiates the relationship between the DA converter resolution and frequency calibration of disciplined clock.
