General Description
Aeroflex Circuit Technology Models ARX4810 ARX4810FP generation monolithic transceivers which provide full compliance with MIL-STD-1553 Macair data requirements smallest packages with power consumption power supply operation. dual channel Model ARX4810 Model ARX4810FP perform front-end analog function inputting outputting data through transformer MIL-STD-1553 Macair data bus. Design these transceivers reflects particular attention active filter performance.This results word error rate with superior waveform purity minimal zero crossover distortion. Efficient transmitter electrical thermal design provides internal power dissipation heat rise high well duty cycles. Each channel dual transceiver completely separate from other fully independent. This includes power leads well signal lines. Hence, each channel connected different data with interaction.
