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. Transmitter The Transmitter section accepts bi-phase TTL data at the input and when coupled to the data bus as per Figure 3 or 4 and by two 70 Ohm terminations (ZO), the data bus signal produced is 6.5 Volts minimum P-P at A-A’.
