INTRODUCTION

The monolithic UT63M14x Transceivers are complete
transmitter and receiver pairs for MIL-STD-1553A and 1553B
applications. Encoder and decoder interfaces are idle low.

The receiver section of the UT63M14x 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
at its TXIN and TXIN and produces MIL-STD-1553 data
signals. The transmitter’s output voltage is typically
12 V

PP, L-L

. Activating the TXIHB input or setting both data

inputs to the same logic level disables the transmitter outputs.

The UT63M14x series offers complete transmitter and receiver
pairs packaged in a dual-channel 36-pin DIP or 24-lead flatpack
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-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.

Table 1. Transmit Operating Mode

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

1

The designer can connect the UT63M14x 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 feet.
Figure 5 shows various examples of bus coupling
configurations. The UT63M14x series transceivers are designed
to function with MIL-STD-1553A and 1553B compatible
transformers.

Note:

1.The 24-lead flatpack internally connects TXOUT to RXIN and TXOUT to
RXIN for each channel.

RECOMMENDED THERMAL PROTECTION

All packages 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 thermally­conductive 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.
