CIRCUIT TECHNOLOGY
General Description:
The Aeroflex Laboratories transceiver
model ARX4808 is a new generation
Dual monolithic transceiver which
provides full compliance with Macair
and
MIL-STD-1553
data
bus
requirements
The model ARX4808 performs the
front-end analog function of inputting
and outputting data through a
transformer to a MIL-STD-1553 or
Macair data bus. The ARX4808 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.
Design of this transceiver 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 ARX4808
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.The
receiver input threshold is set
Internally.
