    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.  
    ARX4810 Dual Universal Transceiver  
    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.

    The Transmitter section accepts

    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.)  
    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,  
    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.

    “INHIBIT  
    input  
    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  
    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.)

    a
    pre-determined  
    Receiver Logic  
    The transceiver utilizes an active  
    filter to suppress harmonics above
