General Description
The Aeroflex Circuit Technology
ACT4454 / 4460 series are next
generation monolithic transceiver
designs which provides full
compliance with MIL-STD-1553A/B
and MacAir A3818, A5690, A5232 &
A4905 requirements in the smallest
packages with low power
consumption and single power supply
operation.
The ACT4454 / 4460 series
performs the front-end analog
function of inputting and outputting
data through a transformer to the
MIL-STD-1553 data bus.
The ACT4454 / 4460 series 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 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.
