General Description
The Aeroflex Circuit Technology
Models ARX4810 and ARX4810FP
are new generation monolithic
transceivers which provide full
compliance with MIL-STD-1553 and
Macair data bus requirements in the
smallest packages with low power
consumption and two power supply
operation.
The dual channel Model ARX4810
and Model ARX4810FP perform the
front-end analog function of inputting
and outputting data through a
transformer to a MIL-STD-1553 or
Macair 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 completely 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.
