General Description
The Aeroflex Laboratories
transceiver models ARX4404 and
ARX4407 are new generation
monolithic transceivers which provide
full compliance with Macair and
MIL-STD-1553 data bus
requirements
The model ARX4404 and model
ARX4407 perform the front-end
analog function of inputting and
outputting data through a transformer
to a MIL-STD-1553 or Macair data
bus. The ARX4404 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
ARX4407 is compatible with
MIL-STD-1553A and 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 ARX4404
series active filter design has
additional high frequency roll-off to
provide the required Macair low
harmonic distortion waveform without
increasing the pulse delay
characteristics significantly.
Efficient transmitter electrical and
thermal design provides low internal
power dissipation and heat rise at
high and well as low duty cycles.
An optional receiver input threshold
adjustment can be accomplished by
the use of the "Set Internal
Threshold" terminals.
Transmitter
The Transmitter section accepts
bi-phase TTL data at the input and
