General Description:

The Aeroflex Circuit Technology

ACT4455 / 4459 series are next

generation

monolithic

transceiver

designs

which

provides

full

compliance with MIL-STD-1553A/B

and

1760

requirements

in

the

smallest packages with low power

consumption and single power supply

operation.

The

ACT4455

/

4459

series

performs

the

front-end

analog

function of inputting and outputting

data through a transformer to the

MIL-STD-1553 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.

Transmitter:

The Transmitter section accepts

bi-phase TTL data at the input and

when coupled to the data bus with a

1:2.5 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 A-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,
