– Data Bus Modules For The Future SCD4487 REV B 1/29/98
General Description
The
Technology ACT 4487 is a next
generation monolithic transceiver
design
which
compliance to MIL-STD-1553A/B
and 1760 requirements in a small
package
with
consumption.
The ACT 4487 series performs
the front-end analog function of
inputting
and
through a transformer to the
MIL-STD-1553 data bus.
Design of this transceiver 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.
transmitter electrical and thermal
design provides low internal power
dissipation and heat rise at high as
well as low duty cycles.
Transmitter:
The Transmitter section accepts
bi-phase TTL data at the input and
when coupled to the data bus with a
1.4:1 ratio transformer, isolated on
the data bus side with two 52.5
Ohm fault isolation resistors, and
loaded
by
two
terminations, the data bus signal is
typically 7.5 Volts P-P at point A
(See Figure 5). When both DATA
and DATA inputs are held low or
high,
the
transmitter
becomes a high impedance and is
“removed” from the line. In addition,
