General Description

The Aeroflex Circuit Technology

ACT4454 / 4460 series are next

generation

monolithic

transceiver

designs

which

provides

full

compliance with MIL-STD-1553A/B

and MacAir A3818, A5690, A5232 &

A4905 requirements in the smallest

packages

with

low

power

consumption and single power supply

operation.

The

ACT4454

/

4460

series

performs

the

front-end

analog

function of inputting and outputting

data through a transformer to the

MIL-STD-1553 data bus.

The ACT4454 / 4460 series can be

considered a "Universal" Transceiver

in

that

it

is

compatible

with

MIL-STD-1553A & B, Macair A-3818,

A-4905, A-5232 and A-5690.

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.

Transmitter:

The Transmitter section accepts

bi-phase TTL data at the input and
