The ACT4453 / 4463 series performs the front-end analog function of inputting and outputting data through a transformer to the MIL-STD-1553 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. Each channel of the dual transceiver is pletely 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. .aeroflex./act1.htm CIRCUIT TECHNOLOGY TX DATA OUT TX DATA IN TX DATA IN DRIVER ACTIVE FILTER OUTPUT STAGE TX DATA OUT TX INHIBIT RX DATA OUT P. +5 V REFERENCE +5V RTN Transmitter: INPUT AMPLIFIER ACTIVE FILTER RX DATA OUT P.
