March 1997 CMOS ARINC Bus Interface Circuit Features Description ARlNC Specification 429 Compatible The HS-3282 is a high performance CMOS bus interface
circuit that is intended to meet the requirements of ARINC
Specification 429, and similar encoded, time multiplexed
serial data protocols. This device is intended to be used with
the HS-3182, a monolithic Dl bipolar differential line driver
designed to meet the specifications of ARINC 429. The
ARINC 429 bus interface circuit consists of two (2) receivers
and a transmitter operating independently as shown in
Figure 1. The two receivers operate at a frequency that is
ten (10) times the receiver data rate, which can be the same
or different from the transmitter data rate. Although the two
receivers operate at the same frequency, they are
functionally independent and each receives serial data asynchronously. The transmitter section of the ARINC bus
interface circuit consists mainly of a First-In First-Out (FIFO)
memory and timing circuit. The FIFO memory is used to hold
up to eight (8) ARINC data words for transmission serially.
The timing circuit is used to correctly separate each ARINC
word as required by ARINC Specification 429. Even though
ARINC Specification 429 specifies a 32-bit word, including
parity, the HS-3282 can be programmed to also operate with …
