General Description
The Aeroflex Circuit Technology
Models ARX4810 and ARX4810FP
are new generation monolithic
transceivers which provide full
compliance with MIL-STD-1553 and
Macair data bus requirements in the
smallest packages with low power
consumption and two power supply
operation.
The dual channel Model ARX4810
and Model ARX4810FP perform the
front-end analog function of inputting
and outputting data through a
transformer to a MIL-STD-1553 or
Macair data bus.
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.
Efficient
transmitter electrical and thermal
design provides low internal power
dissipation and heat rise at high as
well as low duty cycles.
Each channel of the dual transceiver
is completely separate from the other
and fully independent. This includes
power leads as well as signal lines.
Hence, each channel may be
connected to a different data bus with
no interaction.

Block Diagram (without transformer), 1/2 of unit shown
The Transmitter section accepts
bi-phase TTL data at the input and
when coupled to the data bus with a
1:1 transformer, isolated on the data
bus side with two 52.5 Ohm fault
isolation resistors, and loaded by two

70 Ohm terminations plus additional
receivers, the data bus signal
produced is 7.5 volts nominal P-P at
A-A’. (See Figure 5) When both
DATA and DATA inputs are held low
or high, the transmitter output
becomes a high impedance and is
“removed” from the line. In addition,
an
overriding
“INHIBIT
input
provides for the removal of the
transmitter output from the line. A
logic “1” applied to the “INHIBIT”
takes priority over the condition of
the data inputs and disables the
transmitter. (See Transmitter Logic
Waveform, Figure 1.)
The transceiver utilizes an active
filter to suppress harmonics above
1 MHz to meet Macair specifications
A-3818, A-4905, A-5232 and
A-5690. The Transmitter may be
safely operated at 100% duty
cyclefor an indefinite period into a
short circuited, the 1553 or Macair
bus.
The pre-set internal thresholds will
detect data bus signals exceeding
1.150 Volts P-P and reject signals
less than 0.6 volts P-P when used
with a 1:1 turns ratio transformer.
(See Figure 5 for transformer data
and typical connection.)
Receiver
The Receiver section accepts
bi-phase differential data at the input
and produces two TTL signals at the
output. The outputs are DATA and
DATA, and represent positive and
negative excursions of the input
beyond
a
pre-determined
threshold.(See
Receiver

NOTES:
1. DATA and DATA inputs must be complementary waveforms or 50% duty cycle average, with no delays between them.
