INTRODUCTION

The monolithic UT63M1XX Transceivers are complete
transmitter and receiver pairs conforming fully to MIL-STD-

1553A and 1553B. Encoder and decoder interfaces are idle low.

UTMC’s advanced bipolar technology allows the positive
analog power to range from +5V to +12V or +5V to +15V,
providing more flexibility in system power supply design.

The receiver section of the UT63M1XX series accepts biphase­modulated Manchester II bipolar data from a MIL-STD-1553

data bus and produces TTL-level signal data at its RXOUT and

RXOUT outputs. An external RXEN input enables or disables
the receiver outputs.

The transmitter section accepts biphase TTL-level signal data

signals. The transmitter’s output voltage is typically 42VPP, L-

the same logic level disables the transmitter.

The UT63M1XX series offers a monolithic transmitter and
receiver packaged in either single channel (24-pin) or dual­channel (36-pin) configurations designed for use in any MIL­STD-1553 application.

TRANSMITTER

The transmitter section accepts Manchester II biphase TTL data
and converts this data into differential phase-modulated current
drive. Transmitter current drivers are coupled to a MIL-STD­1553 data bus via a transformer driven from the TXOUT and
TXOUT terminals. Transmitter output terminals’ non­transmitting state is enabled by asserting TXIHB (logic 1), or
by placing both TXIN and TXIN at the same logic level. Table
1, Transmit Operating Mode, lists the functions for the output
data in reference to the state of TXIHB. Figure 3 shows typical
transmitter waveforms.

RECEIVER

The receiver section accepts biphase differential data from a
MIL-STD-1553 data bus at its RXIN and RXIN inputs. The
receiver converts input data to biphase Manchester II TTL
format and is available for decoding at the RXOUT and RXOUT
terminals. The outputs RXOUT and RXOUT represent positive
and negative excursions (respectively) of the inputs RXIN and
RXIN. Figure 4 shows typical receiver output waveforms.

Models UT63M105, UT63M107, UT63M125, and UT63M127
idle in the “0” state when disabled or receiving no signal.

POWER SUPPLY VOLTAGES

The UT63M1XX series meets device requirements over a wide
range of power supply voltages. Table 2 shows the overall
capabilities of all available devices. Each channel of the dual
transceiver is electrically and physically separate from the other
and fully independent, including all power and signal lines. Thus
there will be no interaction between the channels.

Notes:

1. x = Don’t care.

2. Transmitter output terminals are in the non-transmitting mode during Off
time.

3. Transmitter output terminals are in the non-transmitting mode during Off
time, independent of TXIHB status.

DATA BUS INTERFACE

The designer can connect the UT63M1XX to the data bus via a
short-stub (direct-coupling) connection or a long-stub
(transformer-coupling) connection. Use a short-stub connection
when the distance from the isolation transformer to the data bus
does not exceed a one-foot maximum. Use a long-stub
connection when the distance from the isolation transformer
exceeds the one-foot maximum and is less than twenty-five feet.
Figure 5 shows various examples of bus coupling
configurations. The UT63M1XX series transceivers are
designed to function with MIL-STD-1553A and 1553B
compatible transformers.

RECOMMENDED THERMAL PROTECTION

All packages, single and dual, should mount to or contact a heat
removal rail located in the printed circuit board. To insure proper
heat transfer between the package and the heat removal rail, use
a thermally conductive material between the package and the
heat removal rail. Use a material such as Mereco XLN-589 or
equivalent to insure heat transfer between the package and heat
removal rail.

Notes:

1.Package material: opaque ceramic.

2.All package finishes are per MIL-PRF-38535.

3.It is recommended that package ceramic be mounted on a heat removal
rail in the printed circuit board. A thermally conductive material should
be used.
