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 biphase-

modulated 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.

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 dual-

channel (36-pin) configurations designed for use in any MIL-

STD-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-STD-

1553 data bus via a transformer driven from the TXOUT and

TXOUT terminals. Transmitter output terminals’ non-

transmitting 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. Figure 4. Typical Receiver Waveforms
