ETC1 BUS-8559-580S Variable output mil-std-1553 transceiver Datasheet

BUS-8559
VARIABLE OUTPUT
MIL-STD-1553 TRANSCEIVER
FEATURES
DESCRIPTION
Designed specifically for use in automatic test equipment where a variable
transmitter output level is required,
the DDC Model BUS-8559 transceiver is a complete transmitter and
receiver conforming to MIL standards
1553A and 1553B.
The receiver section accepts phasemodulated bipolar data at the input
and produces a bi-phase TTL signal
at the output, see FIGURE 1.
Outputs, DATA and DATA, are positive and negative excursions of the
input beyond an internally fixed
threshold. The positive and negative
thresholds are internally set at the
factory for a nominal 1 V pk-pk signal,
when measured at point “A” in FIGURE 2. An external strobe input is
provided which allows the the receiver to be removed from the line. A logic
“0” applied to RECEIVER STROBE
will disable the receiver output.
The BUS-8559 transmitter section
accepts bi-phase TTL data at the
input and produces a nominal 0 to 27
V pk-pk differential output across a
145 Ω load. When the transmitter is
• Variable Transmitter Output
coupled to the data bus with the specified transformer*, and isolated (on the
data side) with two 55 Ω fault isolation
resistors, and loaded with two 70 Ω
terminations
(plus
additional
receivers), the data bus signal produced is a nominal 0 to 7.5 V pk-pk
when measured at the output side of
the 55 Ω resistors.
• Transmitter/Receiver in a Single
24-Pin DDIP Hybrid
• Very Low Power Dissipation
• Improved Receiver Filtering
Enhances System Bit Error Rate
When both DATA and DATA, inputs
are held low or high, the transmitter
presents a high impedance to the
line. An external inhibit input is also
provided, which allows the the transmitter output to be removed from the
line.. When a logic “1” is applied to the
TX INHIBIT input, the transmitter is
disabled, and the data inputs are
ignored.
• Meets MIL-STD-1553A and 1553B
• Power Supplies:
±15 V or
+15 V and -12 V
APPLICATION
The BUS-8559 is suitable for any
MIL-STD-1553 application which
requires a transceiver. The BUS-8559
comes in a hermetic, 24-pin DDIP
package which measures 1.4 x 0.8 x 0.2
inches.
