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.

RX DATA OUT Transmitter The Transmitter section accepts bi-phase TTL data at the input and when coupled to the data bus with a Block Diagram (without Transformer) EROFLEX CIRCUIT TECHNOLOGY - Data Bus Modules for the Future ©SCD4404 REV D 10/27/99 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 7.0 Volts minimum 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 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. 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 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.) 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 +5 Volts is recommended. Figure 1 - Transmitter Logic Waveforms DATA IN DATA IN INHIBIT LINE TO LINE OUTPUT Notes: 1. Line to line waveforms illustrate Macair signals, MIL-STD-1553 signals are trapezoidal 2. DATA and DATA inputs must be complementary waveforms or 50% duty cycle average, with no delays between them. 3. DATA and DATA must be in the same state during off time (both high or low).
