Dual Transceivers for MIL-STD-1553

Features

CIRCUIT TECHNOLOGY

• World’s smallest and lowest standby power dual

transceiver 0.3" x 1" packages

www.aeroflex.com

General Description

• Dual transceiver meets military data bus

The Aeroflex Circuit Technology

requirements, MIL-STD-1553 and MIL-STD-1760

• Low power dissipation at full output power

• Single +5V power supply

Model ACT4468D is

generation D.I. monolithic transceiver

which provide full compliance with

MIL-STD-1553/1760 and data bus

requirements

the

smallest

• Current source output

• Monolithic construction using dielectrically

isolated(D.I.)

packages with the lowest standby

power consumption and one power

supply operation.

The dual channel Model ACT4468D

perform the front-end analog function

of inputting and outputting data

• Processed and screened to MIL-STD-883 specs

• DESC SMD# 5962–92061 Pending

through

transformer

MIL-STD-1553/1760 data bus.

Design of these transceivers reflects

particular attention to active filter

performance. This results in low bit

and word error rate with superior

waveform purity and minimal zero

crossover

distortion.

Efficient

transmitter electrical and thermal

design provides low internal power

dissipation and heat rise at high as

well as low duty cycles.

Each channel of the dual transceiver

is completely separate from the other

and fully independent. This includes

power leads as well as signal lines.

Hence, each channel may be

connected to a different data bus with

no interaction.

TX DATA IN

The Transmitter section accepts

bi-phase TTL data at the input and

when coupled to the data bus with a

1:2.5 transformer, isolated on the

data bus side with two 52.5 Ohm fault

isolation resistors, and loaded by two

70 Ohm terminations plus additional

receivers, the data bus signal

produced is 7.5Volts nominal P-P at

A-A’. (See Figure 5.) When both

DATA and DATA inputs are held low or

high, the transmitter output becomes
