Design and Implementation of Aerospace FC-AE-1553 High Speed Communication Board Based on EMIF Interface

With the continuous development of the aerospace industry, the number of spacecraft in orbit missions is increasing. Traditional bus communication systems are no longer able to meet the growing demands of tasks. To meet the demand for fiber optic communication in spacecraft, a high-speed communication board design scheme for aerospace FC-AE-1553 based on EMIF interface is proposed. This plan is carried out from the aspects of FC-AE-1553 high-speed communication board product definition, overall product design, EMIF bus protocol design, etc. This scheme designs a FC-AE-1553 high-speed communication board that meets the long-term stable communication needs of spacecraft in orbit. The FC-AE-1553 high-speed communication board has two hot backup optical ports connected to the FC-AE-1553 network controller and one EMIF interface connected to user devices. The board mainly realizes the communication function between the load and FC-AE-1553 network controller. The board has been developed and successfully applied to data transmission for multiple spacecraft.
