TheAeroflex Circuit Technology CT 4436 is a next generation monolithic transceiver design which provides full compliance to MIL-STD-1553A/B and1760 re- uirements in a smaller package with lower pin count then the CT4487D, for those designs with less board space.
The ACT 4436 series performs the front-end analog function of inputting and outputting data through a transformer to the MIL-STD-1553 data bus.
Design of this transceiver ACT 4436 series 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.
Transmitter ACT 4436 series: The Transmitter section accepts bi-phase TTL data at the input and when coupled to the data bus with a 1.4:1 ratio transformer, isolated on the data bus side with two 52.5 Ohm fault isolation resistors, and loaded by two 70 Ohm terminations, the data bus signal is typically 7.5 Volts P-P at point 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,
