General Description

The

Aeroflex

Circuit

Technology ACT 4487 is a next

generation monolithic transceiver

design

which

provide

full

compliance to MIL-STD-1553A/B

and 1760 requirements in a small

package

with

low

power

consumption.

The ACT 4487 series performs

the front-end analog function of

inputting

and

outputting

data

through

a

transformer

to

the

MIL-STD-1553 data bus.

Design of this transceiver 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:

The Transmitter section accepts

bi-phase TTL data at the input and

when coupled to the data bus with a

1.4:1 ratio transformer, isolated on

the data bus side with two 52.5

Ohm fault isolation resistors, and

loaded

by

two

70

Ohm

terminations, the data bus signal is

typically 7.5 Volts P-P at point A

(See Figure 5). When both DATA

and DATA inputs are held low or

high,

the

transmitter

output

becomes a high impedance and is

“removed” from the line. In addition,

an

overriding

“INHIBIT"

input
