A3818

The Aeroflex Laboratories transceiver model ACT4808 is a new generation Dual monolithic transceiver which provides full compliance with Macair and MIL-STD-1553 data bus requirements The model ACT4808 performs the front-end analog function of inputting and outputting data through a transformer to a MIL-STD-1553 or Macair data bus. The ACT4808 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 this transceiver 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 ACT4808 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.The receiver input threshold is set Internally.
