ETC BU-63149D3-822S

BU-63147 and BU-63149
MIL-STD-1553 DATA BUS
+5V TRANSCEIVER
FEATURES
DESCRIPTION
The BU-63147/49 transceiver is a complete dual transmitter and receiver pair
conforming fully to MIL-STD-1553A
and 1553B. Features include: monolithic design, +5V power supply voltage,
Harris or Smiths type decoder interface, completely independent dual
redundant operation, and small size
(36 pin DIP). The receiver section of
the BU-63147/49 series accepts
phase-modulated bipolar data from a
MIL-STD-1553 Data Bus and produces TTL Signal data at its output.
RX DATA OUT and RX DATA OUT
These outputs represent positive and
negative variations of the input data
signals beyond an internally fixed
threshold level. An external STROBE
input enables or disables the receiver’s
outputs.
The transmitter section accepts
bi-phase TTL signal data at its
TX DATA IN and TX DATA IN inputs
and produces phase-modulated
bipolar data at the TX DATA OUT and
TX DATA OUT outputs.
The
transmitter’s output voltage level is
typically about 11Vpp. An external
input, INHIBIT, takes priority over the
transmitter inputs and disables the
transmitter when activated with a logic
“1”.

Notes:
Notes 1 through 6 are applicable to the Receiver Differential Resistance and
Differential Capacitance specifications:
(1) Specifications include both transmitter and receiver (assumed tied together
externally).
(2) Impedance parameters are specified directly between pins TX/RX A(B) and
TX/RX A(B) hybrid.
(3) It is assumed that all power and ground inputs to the hybrid are connected and
that the hybrid case is connected to ground for the impedance measurement.

TABLE 2. TRANSMIT OPERATING MODE
Notes (continued)
(4) The specifications are applicable for both unpowered and powered conditions.
(5) The specifications assume a 2 volt rms balanced, differential, sinusoidal input.
The applicable frequency range is 75 kHz to 1 MHz.
(6) Minimum resistance and maximum capacitance parameters are guaranteed
over the operating range, but are not tested.
(7) The Threshold Level, as referred to in this specification, is meant to be the

The receiver section accepts data from a MIL-STD-1553 Data
Bus when coupled to the Data Bus as shown in FIGURE 3. This
data is converted to bi-phase TTL and furnished to
RX DATA OUT and RX DATA OUT .
(9) MIL-STD-1760 requires minimum output voltage of 20 Vp-p on the stub connection. The -XX2 option is not available for the BU-63147X4 version.
(10) Power dissipation specifications assume a transformer coupled configuration, with external dissipation (while transmitting) of 0.14 watts for the active
isolation transformer, 0.08 watts for the active coupling transformer, 0.45 watts

bus termination resistors.
As illustrated in FIGURE 2, the receiver in the BU-65147 provides compatibility to the Harris decoder, while the BU-63149
provides compatibility to the Smiths decoder.
INTRODUCTION
The BU-63147/49 is a dual redundant transmitter and receiver
packaged in a 36-pin DDIP. It is directly compatible to Harris
15530 encoder/decoder and has internal (factory preset) threshold levels. The dual transceiver only requires +5V power and
conforms to MIL-STD-1553A and 1553B. For McAir compatability, versions are available with rise/fall times of 200 to 300 nsec.
WAVEFORMS
FIGURE 2 illustrates the BU-63147 with Harris type decoder
interface and the BU-63149 with Smiths type decoder interface.
Note that DATA and DATA inputs must be complementary waveforms with a 50% duty cycle.
FIGURE 3 illustrates the connection between a BU-63147/49
transceiver and a MIL-STD-1553 Data Bus. After transformer
isolating the transceiver, it can be either direct coupled (short
stub) or transformer coupled (long stub) to the Data Bus.

The transmitter section accepts encoded TTL data and converts
it to phase-modulated bipolar form using a waveshaping network
and driver circuits. The driver outputs TX DATA OUT and
TX DATA OUT are transformer coupled to the Data Bus.
RX Data Out

The transmitter output terminals can be put into a high impedance state by setting INHIBIT high, or setting TX DATA IN and
TX DATA IN to the same logic level. The operating modes are
shown in TABLE 2.

Notes:
(1) TX Data In and RX Data Out are TTL signals.
(2) TX Data In inputs must be at opposite logic levels during transmission, and at
the same logic level when not transmitting.
(3) LINE-TO-LINE output voltage is measured between TX Data Out and TX Data Out.
(4) LINE-TO-LINE input voltage is measured on the Data Bus.
The transceivers are able to operate in a “wraparound” mode.
This allows output data to be monitored by the receiver section
and returned to the decoder where it is checked for errors.

Interfacing the BU-63147/49 to a MIL-STD-1553 bus requires a
pair of pulse transformers. Beta Transformer Technology
Corporation (BTTC), a subsidiary of DDC, manufactures transNOTES:
1.
For the BU-63147/49X4-XX0 versions, which include McAIR compatible transceivers, only the B-3818 or B-3819 transformers
(shown in bold in the table) may be used.
2.
For the BU-63147/49X3-XXX versions with 1553B (and possibly 1760) transceivers, any of the other transformers listed may be used.
3.
There are no BU-63147/49X4-XX2 versions.
