GENERAL DESCRIPTION
The Aeroflex Plainview transceiver model ARX4404 and is a new generation monolithic transceiver which provide full compliance
with Macair and MIL-STD-1553 data bus requirements. The model ARX4404 and ARX4407 performs 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 Macair (A-3818, A-4905, A-5232 and
A-5690), MIL-STD-1553A/B and SAE-AS1553. The ARX4407 is compatible with MIL-STD-1553A/B and SAE-AS15531.
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 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 low duty cycles.
An optional receiver input threshold adjustment can be accomplished by the use of the ''External Threshold" terminals or use of the
"Set Internal Threshold" terminals.
TRANSMITTER
The Transmitter section accepts bi-phase TTL data at the input and when coupled to the data bus with a 1:1 transformer the data bus
signal produced is 7.0 Volts minimum P-P at point 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 Waveforms - Figure 1).
The transmitter 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 for an indefinite period at 100% duty cycle into a data bus short circuit.
The transceiver utilizes an active filter to suppress harmonics above 1MHz. The Transmitter may be safely operated at 100% duty
cycle for an indefinite period into a short circuited 1553 bus.
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
Logic Waveforms - Figure 2).
The internal threshold is nominally set to detect data bus signals exceeding 1.05 Vp-p and reject signals less than 0.6 Vp-p when
used with a 1:1 turns ratio transformer (See Figure 3 or 4 for transformer data and typical connection). This threshold setting can be
held by grounding the appropriate pins or modified with the use of external resistors.
A low level at the ''STROBE'' input inhibits the DATA and DATA outputs. If unused, a 2K Ohm pull-up to +5V
DC
is recommended.
