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.
Transmitter
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.
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 Waveform Figure 2).
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.)
