【Abstract】 An overall scheme of FC-AE-1553 interface circuit based on PON structure is designed to further simplify the structure of avionics systems and meet the requirements of high performance and low power consumption of the avionics environment. The FTCS-OLE-20B and FEU3411S-2DT-1 chip is used to perform photoelectric conversion of FPGA signals,and the PON(passive optical network)is formed by optical splitter to carry out data transmission. The loopback test platform is used for functional testing and verification. The experimental results show that the designed interface circuit can not only meet the functional requirements of the FC-AE-1553 device for the bottom layer optical fiber protocol,but also has verified its transmission characteristics of low delay,strong anti-interference and high transmission rate.更多还原
