General Description

The

Aeroflex

Laboratories

transceiver models ARX4404 and

ARX4407

are

new

generation

monolithic transceivers which provide

full

compliance

with

Macair

and

MIL-STD-1553

data

bus

requirements

The model ARX4404 and model

ARX4407

perform

the

front-end

analog

function

of

inputting

and

outputting data through a transformer

to a MIL-STD-1553 or Macair data

bus.

The

ARX4404

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. The

ARX4407

is

compatible

with

MIL-STD-1553A and B.

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. The ARX4404

series

active

filter

design

has

additional high frequency roll-off to

provide

the

required

Macair

low

harmonic distortion waveform without

increasing

the

pulse

delay

characteristics significantly.

Efficient transmitter electrical and

thermal design provides low internal

power dissipation and heat rise at

high and well as low duty cycles.

An optional receiver input threshold

adjustment can be accomplished by

the

use

of

the

"Set

Internal

Threshold" terminals.

Transmitter

The Transmitter section accepts

bi-phase TTL data at the input and

when coupled to the data bus with a
