Description
The RM3183 is a dual line receiver designed to meet all
requirements of the ARINC 429 interface specification.
It contains two independent receiver channels which accept
differential input signals and converts them to serial TTL
data.
Input overvoltage protection is provided by special circuitry
including dielectrically-isolated thin-film resistors and
clamping diodes. Self-test logic inputs are provided for
internal system tests. These inputs force the outputs to
either a high, a low, or a null state for off-line system tests.
Input noise filtering is accomplished with external capaci-
tors. Two are required for each channel and can be adjusted
for best noise immunity at a specific data rate.
Three power supplies are needed plus ground. The input
thresholds depend only on the logic supply, so a wide range
of dual supplies can be accommodated.
The Raytheon RM3183 line receiver is the companion chip
to the RM3182 line driver. Together they provide all the
analog functions needed for the ARINC 429 interface.
Digital data processing involving serial-to-parallel conver-
sion and clock recovery can be accomplished using one of
the ARINC interface ICs available or by discrete or gate
array implementations.
