General Description
The
Aeroflex
Circuit
Technology model ACT4469D is a
next
generation
monolithic
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
outputting
data
through
a
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.
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.
Variable amplitude is adjusted
with factory preset 0鈥?0Vdc control
line at 2 mA maximum input current
at 10 Volts.

The
Transmitter
section
accepts complementary TTL data
at the input, and when coupled to
the data bus with a 1:1 transformer,
isolated on the transceiver side with
two 34 ohm fault isolation resistors,
and loaded by a 175 ohm
termination, the data bus signal
produced is 20 Volts nominal P-P at
COMP.
