ARINC 429
Serial Transmitter and Dual Receiver
GENERAL DESCRIPTION
The HI-3282 is a silicon gate CMOS device for interfacing
the ARINC 429 serial data bus to a 16-bit parallel data bus.
Two receivers and an independent transmitter are
provided. The receiver input circuitry and logic are
designed to meet the ARINC 429 specifications for loading,
level detection, timing, and protocol. The ARINC inputs of
the HI-3282-10 configurations also have internal lightning
protection to DO-160D, Level 3. The transmitter section
provides the ARINC 429 communication protocol. An
external ARINC 429 Line Driver such as the Holt HI-3182 or
HI-8585 is required to translate the 5 volt logic outputs to
ARINC 429 drive levels.
The 16-bit parallel data bus exchanges the 32-bit ARINC
data word in two steps when either loading the transmitter
or interrogating the receivers. The data bus interfaces with
CMOS and TTL.
Timing of all the circuitry begins with the master clock input,
CLK. For ARINC 429 applications, the master clock
frequency is 1 MHz.
Each independent receiver monitors the data stream with a
sampling rate 10 times the data rate. The sampling rate is
software selectable at either 1MHz or 125KHz. The results
of a parity check are available as the 32nd ARINC bit.
The transmitter has a First In, First Out (FIFO) memory to
store 8 ARINC words for transmission. The data rate of the
transmitter is software selectable by dividing the master
clock, CLK, by either 10 or 80. The master clock is used to
set the timing of the ARINC transmission within the required
resolution.
The HI-3282BPJx product has a minimum low speed data
rate of 6.5K BPS.
