BU-63133L8
MIL-STD-1553 DATA BUS
3.3 VOLT SINGLE TRANSCEIVER
DESCRIPTION
The BU-63133 transceiver is a complete transmitter and receiver con-
forming fully to MIL-STD-1553A, 1553B, and 1760. The use of two
BU-63133 transceivers provides full dual redundancy. Features
include: +3.3V power supply voltage, Harris interface type, and a ultra
low profile, small footprint, 32-pad Leadless Plastic Chip Carrier pack-
age (LPCC). The LPCC package provides an integral, exposed
heatsink on the package bottom. This package allows 100% duty
cycle operation at 125°C when the heatsink is soldered to an appro-
priately constructed PCB.
The receiver section of the BU-63133 accepts Manchester II data
from a MIL-STD-1553 Data Bus and produces TTL level signals at its
outputs: RX DATA OUT and RX DATA OUT. These outputs represent
positive and negative excursions 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 bipolar TTL signal data at its TX
DATA IN and TX DATA IN inputs and produces Manchester II data at
the TX DATA OUT and TX DATA OUT outputs.
When used with the recommended transformers, the transmitter typ-
ically produces 21 Vp-p for transformer coupled outputs and 7 Vp-p at
the bus. An external input, TX INHIBIT, takes priority over the trans-
mitter inputs and disables the transmitter when activated with a logic

ance with MIL-STD-1553A, 1553B, and 1760 simplify engineering
design, making it an excellent choice for interfacing with any MIL-
STD-1553 system.

(7) The Threshold Level, as referred to in this specification, is meant to be the maximum peak-to-peak voltage (measured on the stub) that can be applied to the receiver's
input without causing the output to change from the OFF state.
TABLE 1 Notes (Continued):
(8) Assumes a common mode voltage within the frequency range of dc to 2 MHz, applied to pins of the isolation transformer on the stub side (either direct or transformer
coupled), and referenced to hybrid ground. Transformer must be a DDC recommended transformer or other transformer that provides an equivalent minimum CMRR.
(9) MIL-STD-1760 requires minimum output voltage of 20Vp-p on the stub connection
(10) Current drain and power dissipation specifications are preliminary and subject to change.
(11) Power dissipation specifications assume a transformer coupled configuration with external dissipation (while transmitting with 100% duty cycle) of 1.25W, which is
composed of 0.14 watts for the active isolation transformer, 0.08 watts for the active bus coupling transformer, 0.45 watts for EACH of the two bus isolation resistors and
0.15 watts for EACH of the two bus termination resistors.
(12) Uses BETA Transformer Technology Corporation, B-3372/LVB-4203 transformer for Stub coupling or B-3383/LVB4103 transformer for direct coupled configurations.
(Refer to BETA's web page www.bttc-beta.com)
(13) Thermal resistance specifications are preliminary and subject to change and are with 16 vias connecting heat slug to PCB internal plane. Each via is 0.3 mm diame-
ter and 0.035 mm plating. Refer to JEDEC standard JESD51-9 for detailed PCB construction.
(14) The effective input capacitance, as seen from the 1553 bus, is reduced by the square of the turns ratio of the coupling transformer.
DEVICE OPERATION
When the SLEEP input is asserted (logic "1"), the BU-63133 dis-
ables it's transmitter (both outputs go to a high impedance state)
and receiver (both receiver outputs go to logic "0") and goes into
a power saving mode. If the SLEEP function is not needed, this
pin may be tied low.
Applying a logic "1" to the STROBE input allows data to pass
through to the receiver outputs. Applying a logic "0" to the
STROBE input turns the receiver outputs OFF (both receiver
outputs go to logic "0"). In addition, the receiver outputs are at a
logic "0" when no signal is being received, which is directly com-
patible with a "Harris" type of encoder/decoder.
ables it's transmitter, and both TX Data outputs go to a high
impedance state.
1553 BUS INTERFACE AND LAYOUT
CONSIDERATIONS
FIGURE 2 illustrates the interface between the BU-63133 and a
MIL-STD-1553 bus. Connections for both direct (short stub) and
transformer (long stub) coupling, as well as the peak-to-peak
voltage levels at various points (when transmitting), are indicat-
ed in the diagram. Note that the diagrams do not indicate the
RX/RX pins, which have to be connected to the TX/TX pins and
the transformer primaries.
When the TX INHIBIT input is asserted (logic "1"), or when both
TX Data inputs are at the same logic level, the BU-63133 dis-
The isolation transformers for the BU-63133 series contain only
one set of output windings. Different isolation transformers are

NOTES:
1. Transformer center tap capacitors; a 10µF for low inductance, and a 0.01µF ceramic. Both must be mounted
as close as possible, and with the shortest leads to the center tap of the transformer(s) and ground.
2. The BU-63133 should have its grounds connected as directly as possible to the 3.3V ground plane.
