This paper refers to the work with the interface of information interchange multiplex channel described in GOST R 52070-2003 and foreign standard MIL-STD-1553B. In introduction authors discuss the interface of consumers, operating in a system of information exchange, and the actual modules that function as endpoints in onboard spacecraft equipment. Further attention is given to the module which is actively used nowadays. In the article module’s main disadvantages and problems of using in the spacecraft equipment are specified, the block diagram of the device is presented. The article also presents the current developments associated with the interchange multiplex interface modules and terminal devices that carried out in RPC “Polyus”. Thus, the article presents two versions of modules, based on ASIC N1582VJ2 and N1582VJ3V. The shortcomings of the module, based on ASIC N1582VJ2, are given, further eliminated in the module based on N1582VJ3V. Their structural and functional diagrams are considered, briefly described the principle of operation of the module based on N1582VJ2, and the functioning of the module based on N1582VJ3V is described in more detail. Timing diagrams of the exchange module logic and the switching diagrams of the parallel interface read and write mode to external devices are shown, and the last are described in detail. A photo of the multiplex channel module based on N1582VJ3V is presented. Next, the authors publish the results of testing the developed module based on N1582VJ3V against GOST R 52070-2003. The verification of compliance to the logical interface protocol, as well as the electrical parameters of the signals, in particular the input and output, is described. The module response to some commands in the form of diagrams is presented and described. The waveforms of electrical signals are shown, and their detailed characteristics are collected in the table. In conclusion, the article gives the tabular comparison of the modules mentioned earlier. In the end, the authors talk about the possible uses of the module in the onboard equipment of spacecraft.
