【应用】国产小型逻辑反相器SGM7SZ04XC5G/TR用于射频探测设备，保证FPGA与外设收发系统间数据传输顺畅
本设计为基于微波原理的射频探测设备，主要用于测绘及人体生命探测方面。主控采用的是FPGA，高速运行的FPGA与射频收发系统之间为了更好地配合，保证数据的传输顺利，因此需要设置缓冲。这里推荐一颗国产的小型逻辑反相器SGM7SZ04XC5G/TR，通过反相器可实现缓冲半个周期数据，从而保证了FPGA与外设收发系统之间数据的传输顺畅。
SGM7SZ04XC5G/TR的特点：
① 该装置可以通过高输出驱动实现超高速运行，超高速：V-CC=3.3V时，t-PD为4.2ns（TYP）至50pF，同时在宽电源电压工作范围内保持低静态功耗。
② 该设备的电源电压引脚接受1.65V至5.5V的任何电压。无论电源电压范围如何，输入都能承6V的电压。当V-CC为0V时，输入和输出处于高阻抗状态。
③ 其输入过压容差时可使5V到3V转换可用。
④ SGM7SZ04系列有绿色UTDFN-1.45×1-6L、SC70-5和SOT-23-5封装。其工作环境温度范围为-40℃至+125℃。
综上所述，可通过高输出驱动实现超高速运行，在宽电源电压工作范围内保持低静态功耗的国产芯片SGM7SZ04XC5G/TR是探测设备中作为FPGA与外设收发系统之间数据缓冲器的理想之选。
