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.
(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 maximum peak-to-peak voltage (measured on the data bus) that can be applied to the
receiver's input without causing the output to change from the OFF state.
(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 transceiver 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 20 Vp-p on the stub connection. The -XX2 option is
not
available for the BU-63147X4 or BU-63157 versions.
(10) Power dissipation specifications assume a transformer coupled configuration, with external dissipation (while transmitting) of 0.14 watts for the active isolation trans-
former, 0.08 watts for the active 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.
(11) Assuming the use of isolation transformers with the turns ratios shown in Figure 3 and in the absence of common mode signal on the 1553 stub, this equates to a
nominal stub voltage of 38 Volts
PK-to-PK
transformer-coupled, or 53 Volts
PK-to-PK
direct-coupled.

INTRODUCTION
The BU-63147/157 is a dual redundant transmitter and receiver
packaged in a 36-pin DDIP or flat pack. 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 compat-
ibility, versions are available with rise/fall times of 200 to 300
nsec.
Figure 3 illustrates the connection between a BU-63147/157
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.
*Note: Radiation parameters specified on this data sheet are derived from initial
qualification testing by DDC and published data from ASIC manufacturers. These
devices have not been evaluated for compliance to the RHA requirements stipu-
lated in MIL-PRF-38534, Appendix G.

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.
The transmitter output terminals can be put into a high imped-
ance 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 4.
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.
