振荡器频率上变频器

AD9552是一款小数N分频、基于锁相环(PLL)的时钟发生器，专为取代高频晶体振荡器和谐振器而设计。该器件采用Σ-Δ调制器(SDM)来处理小数频率合成。用户将单端时钟信号直接与REF引脚相连，或者在XTAL引脚上连接一个晶体谐振器，即可提供输入参考信号。\n\n AD9552为引脚可编程器件，根据8种常用输入频率的其中一种频率，可提供64种标准输出频率中的一种频率。该器件还有一个三线式SPI接口，用户可以通过该接口自定义设置输入与输出频率比。\n\n AD9552需用外部电容来构成PLL的环路滤波器。虽然AD9552严格按照CMOS工艺制造，但其输出与LVPECL、LVD • 将低频输入参考信号转换为高频输出信号\n\n• 输入频率范围：6.6 MHz至125 MHz\n\n• 输出频率最高达900 MHz\n\n• 预设引脚可编程频率转换比;
