Data Device Corporation 100 DS-BU-67301B-Gwww.ddc-web.com 1/148 MIL-STD-1553 TRANSCEIVER OPTIONS8.1 Using the Internal TransceiversMost Total-AceXtreme® applications will involve use of the internal 1553transceivers and transformers. For these applications, the connections shown inFigure 58 will be applicable. This includes making the indicated connections of thedigital signals between the protocol logic chip and the transceivers.The MIL-STD-1553 Core interface signals and internal MIL-STD-1553 signals areimplemented as external signals to specific pins. The user has the option ofconnecting them on the PC board as shown in Figure 58, or connecting the 1553Core interface signals to an external Transceiver. If the internal transceiver is notused, this allows the Total-AceXtreme to be used with MIL-STD-1773 (fiber optic)transceivers. The decoders can also be configured to operate with single-ended inputsignals for interfacing to fiber optic transceivers.Figure 57.
