in a Chipscale Package

Preliminary

CIRCUIT TECHNOLOGY

Features

www.aeroflex.com

• Transceiver meets military data bus requirements,

MIL-STD-1553 and MIL-STD-1760

• Low power dissipation at full output power

• Single +5V power supply

• Current Source Transmitter Output

• Bipolar Monolithic Construction

• Miniature Chipscale Package Bumped Chip Carrier™

General Description

The Aeroflex Circuit Technology

Model ACT4438-1 is

generation monolithic transceiver

which provide full compliance with

MIL-STD-1553/1760 and data bus

requirements in a Bumped Chip

Carrier™ (BCC++) with the lowest

standby power consumption and

single power supply operation.

(BCC++)

The Model ACT4438-1 performs the

front-end analog function of inputting

and outputting data through

transformer to a MIL-STD-1553/1760

Shown 2X

data bus with

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.

Transmitter

Block Diagram (without Transformer)

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 55 Ohm fault

isolation resistors for direct stub

coupling. The data bus signal

produced for RISET = 2.7K Ohm is

typically 7.5 Volts nominal P-P at

A-A’, See Figure 5. When both DATA

and DATA inputs are held low, the

transmitter output becomes a high

impedance and is “removed” from the

line. In addition, an overriding

“INHIBIT" input provides for the

removal of the transmitter output from

the line. A logic “1” applied to the

“INHIBIT” takes priority over the
