General Description
The Aeroflex Laboratories
transceiver models ARX 4418 and
ARX 4417 are new generation
monolithic transceivers which provide
full compliance with Macair and
MIL-STD-1553data bus requirements
while providing variable amplitude
control.
The model ARX 4418 and model
ARX 4417 perform the front-end
analog function of inputting and
outputting data through a transformer
to a MIL-STD-1553 or Macair data
bus. The ARX 4418 can be
considered a "Universal" Transceiver
in that it is compatible with
MIL-STD-1553A, B, Macair A-3818,
A-4905, A-5232 and A-5690. The
ARX 4417 is compatible with
MIL-STD-1553A/B.
Design of these transceivers
reflects particular attention to active
filter performance.This results in low
bit and word error rate with superior
waveform purity and minimal zero
crossover distortion. The ARX4418
series active filter design has
additional high frequency roll-off to
provide the required Macair low
harmonic distortion waveform without
increasingthepulsedelaycharacteris-
tics significantly.
Efficient transmitter electrical and
thermal design provides low internal
power dissipation and heat rise at
high and well as low duty cycles.
Variable amplitude is adjusted with
0–10 Vdc on the control pin. An
optional receiver input threshold
adjustment can be accomplished by
the use of the "Set Internal
Threshold" terminals.
