General Description
The
Aeroflex
Laboratories
Incorporated model ARX4435N and
ARX4435NFP are new generation
monolithic
transceivers
which
provides
compliance
with
Macair
H009 data bus requirements.
The ARX4435N and ARX4435NFP
perform the front-end analog function
of
inputting
and
outputting
data
through a transformer to a H009 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. The ARX4435N
series
active
filter
design
has
additional high frequency roll-off to
provide the required low harmonic
distortion
waveform
without
increasing the delay characteristics
significantly.
Efficient transmitter electrical and
thermal design results in low internal
power dissipation and temperature
rise at high and low duty cycle.
Transmitter
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 35 Ohm
fault isolation resistors, and loaded by
a 170 Ohm termination, the data bus
signal produced is 20 Volts nominal
P-P at A-A’. (See Figure 5.) When
both DATA and DATA inputs are held
low or high, the transmitter output
impedance is low, and signal is
“removed” from the line. In addition,
