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 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 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’ 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:

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.
