htm CIRCUIT TECHNOLOGY General Description The Aeroflex Circuit Technology ACT4418D is a new generation monolithic transceivers which provide full compliance with Macair and MILSTD-1553 data bus requirements while providing variable amplitude control.
The ACT4418D performs the frontend analog function of inputting and outputting data through a transformer to a MIL-STD-1553 or Macair data bus.
The ACT4418D 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.
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 ACT4418D 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.
Variable amplitude is adjusted with 0–10 Vdc on the control pin.
