Most MIL-STD-1553 and STANAG-3838 applications, including for MIL-STD-1760,
require the use of a transceiver providing a trapezoidal waveform, with rise/fall times
in the range of 100 to 300 ns. However, there are some applications that require
compatibility with McAir standards such A3818, A5232, and A5690. For these
applications, a transceiver providing an approximate sinusoidal waveform with
reduced harmonic content, rather than a trapezoidal waveform, must be used. In
addition, the McAir standards require both direct and transformer coupling, and
require connections to the isolation transformer center taps on the stub side.
Figure 59 shows the use of Total-AceXtreme for applications requiring compatibility
with the McAir standards. For this, DDC's BU-67401-L0D0L-100 dual 3.3V
transceiver includes a McAir-compatible transmitter, while Beta Transformer
Technology Corporation's DSS-3300-1 dual transformer provides both direct and
transformer coupled taps, and brings out the center tap connections on the stub
(secondary) side.
