MIL-STD-1553 TRANSCEIVER OPTIONS

8.1

Using the Internal Transceivers

Most Total-AceXtreme® applications will involve use of the internal 1553
transceivers and transformers. For these applications, the connections shown in
Figure 58 will be applicable. This includes making the indicated connections of the
digital signals between the protocol logic chip and the transceivers.
The MIL-STD-1553 Core interface signals and internal MIL-STD-1553 signals are
implemented as external signals to specific pins. The user has the option of
connecting them on the PC board as shown in Figure 58, or connecting the 1553
Core interface signals to an external Transceiver. If the internal transceiver is not
used, 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 input
signals for interfacing to fiber optic transceivers.
