CIRCUIT TECHNOLOGY
General Description:
The Aeroflex Circuit Technology
ACT4458 / 4464 series are next
generation monolithic transceiver
designs
which
provides
full
compliance with MIL-STD-1553A/B
and 1760 requirements in the
smallest packages with low power
consumption and single power supply
operation.
The ACT4458 / 4464 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 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.

Block Diagram (without Transformer)
The Transmitter section accepts
bi-phase TTL data at the input and
when coupled to the data bus with a
1:2.5 ratio transformer, isolated on
the data bus side with two 52.5 Ohm
fault isolation resistors, and loaded by
eroflex Circuit T
