ACT4469D

Dual Variable Amplitude Transceivers

for H009

Features

CIRCUIT TECHNOLOGY

www.aeroflex.com

• World’s smallest and lowest standby power dual

variable amplitude H009 transceiver 1.25" x 0.61"

maximum ceramic package

General Description

The

Technology model ACT4469D is a

next generation monolithic

Aeroflex

Circuit

• Dual transceiver with variable output amplitude

control meets McDonnell Douglas H009 data bus

specifications

transceiver which provides variable

amplitude in compliance with H009

data bus requirements with the

lowest standby power consumption

available using three DC power

supplies operation.

The dual channel model

ACT4469D performs the front-end

analog function of inputting and

• Lowest standby power

• Low power dissipation at full output power

• Operates with 12V to 15 and +5V power supplies

• Voltage source output for transmitter

• Monolithic construction

outputting

data

through

• Processed to commercial or screened to

transformer to a H009 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.

The ACT4469D series active filter

design provides the required H009

low harmonic distortion waveform

without increasing the pulse delay

characteristics significantly.

MIL-STD-883 specs

• +10V Control line for transmitter amplitude

adjustment (See Figure 3)

• Packaging – Hermetic Ceramic

■

Non-conductive mounting surface

No package glass beads

Small size & light weight

Efficient transmitter electrical

and thermal design provides low

internal power dissipation and heat

rise at high and well as low duty

cycles.The receiver input threshold

is set internally.
