General Description
The Aeroflex Circuit Technology
Model ACT4468D is a next
generation D.I. monolithic transceiver
which provide full compliance with
MIL-STD-1553/1760 and data bus
requirements in the smallest
packages with the lowest standby
power consumption and one power
supply operation.
The dual channel Model ACT4468D
perform the front-end analog function
of inputting and outputting data
through a transformer to a
MIL-STD-1553/1760 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.
Transmitter:
The Transmitter section accepts
bi-phase TTL data at the input and
when coupled to the data bus with a
1:2.5 transformer, isolated on the
data bus side with two 52.5 Ohm fault
isolation resistors, and loaded by two
70 Ohm terminations plus additional
receivers, the data bus signal
produced is 7.5Volts nominal P-P at
A-A’. (See Figure 5.) When both
DATA and DATA inputs are held low or
high, the transmitter output becomes
