| BU-63147 and BU-63149 MIL-STD-1553 DATA BUS +5V TRANSCEIVER 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 BU63147/49 series accepts phasemodulated bipolar data from a MIL-STD-1553 Data Bus and produces TTL Signal data at its output. The RX DATA OUT and RX DATA OUT 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". The small size, +5V power supply voltage, and compliance with MIL-STD-1553 simplify engineering design, making it an excellent choice for interfacing with any MIL-STD1553 system.

Data Device Corporation www.ddc-web.com 2 BU-63147/49 B1 web-09/02-0 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 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 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 for each of the two bus isolation resistors, and 0.15 watts for each of the two bus termination resistors.

RECEIVER OPERATING MODE 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 . When STROBE is high data passes through the receiver to RX DATA OUT and RX DATA OUT . Applying a low to STROBE disables the receiver output terminals. 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 compatibility, versions are available with rise/fall times of 200 to 300 nsec. 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. 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. ENCODER OUTPUT (NOTE 2) TX Data In TX Data In LINE-TO-LINE OUTPUT LINE-TO-LINE INPUT XXX XXX XXX XXX TRANSMIT OPERATING MODE 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 impedwww..com INHIBIT high, or setting TX DATA IN and ance state by setting TX DATA IN to the same logic level. The operating modes are shown in TABLE 2. 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. Data Device Corporation www.ddc-web.com RX Data Out BU-63147 RX Data Out RX Data Out BU-63149 RX Data Out 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. FIGURE 2. WAVEFORMS FOR HARRIS/SMITHS TYPE ENCODER/DECODERS 3 BU-63147/49 B1 web-09/02-0 TRANSFORMERS In selecting isolation transformers to be used with the BU63147/49, there is a limitation on the maximum amount of leakage inductance. If this limit is exceeded, the transmitter rise and fall times may increase, possibly causing the bus amplitude to fall below the minimum level required by MIL-STD-1553. In addition, an excessive leakage imbalance may result in a transformer dynamic offset that exceeds 1553 specifications. The maximum allowable leakage inductance is 6.0 H, and is measured as follows: The side of the transformer that connects to the BU-63147/49 is defined as the "primary" winding. If one side of the primary is shorted to the primary center-tap, the inductance should be measured across the "secondary" (stub side) winding. This inductance must be less than 6.0 H. Similarly, if the other side of the primary is shorted to the primary center-tap, the inductance measured across the "secondary" (stub side) winding must also be less than 6.0 H. The difference between these two measurements is the "differential" leakage inductance.This value must be less than 1.0 H. Beta Transformer Technology Corporation (BTTC), a subsidiary of DDC, manufactures transformers in a variety of mechanical configurations with the required turns ratios of 1:2.5 direct coupled, and 1:1.79 transformer coupled.
