General Description
The
Aeroflex
Laboratories
Incorporated model ARX4435 and
ARX4435FP are new generation
monolithic
transceivers
which
provides compliance with Macair
H009 data bus requirements
The
model
ARX4435 and
ARX4435FP perform the front-end
analog function of inputting and out-
putting data through a transformer to
a H-009 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 ARX4435
series active filter design has addi-
tional high frequency roll-off to pro-
vide the required low harmonic
distortion waveform without increas-
ing the delay characteristics signifi-
cantly.
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,
