DESCRIPTION
If enabled, an internal connection
is made passing 429DO and
to the receiver logic inputs
429DO

0 = ENABLE
RECEIVER 1
DECODER
If enabled, ARINC bits 9 and,
10 must match the next two
control word bits
BDO6
1 = ENABLE
If Receiver 1 Decoder is
enabled, the ARINC bit 9
must match this bit

RECEIVER 2
DECODER
If enabled, ARINC bits 9 and
10 must match the next two
control word bits
BDO9
1 = ENABLE
If Receiver 2 Decoder is
enabled, then ARINC bit 9
must match this bit

PARITY
Logic 0 enables normal odd parity
and Logic 1 enables even parity
output in transmitter 32nd bit
BD12
1 = ENABLE
BD13
XMTR DATA
CLK SELECT
0 = ÷10
1 = ÷80
CLK is divided either by 10 or
80 to obtain XMTR data clock
BD14
RCVR DTA
CLK SELECT
0 = ÷10
1 = ÷80
CLK is divided either by 10 or
80 to obtain RCVR data clock
CONTROL WORD REGISTER
The HI-8581 contains 10 data flip flops whose D inputs are con-
nected to the data bus and clocks connected to
flip flop provides options to the user as follows:

Figure 1 shows the input circuit for each receiver. The ARINC 429
specificationrequiresthefollowingdetectionlevels:
The HI-8581 guarantees recognition of these levels with a common
mode Voltage with respect to GND less than ±5V for the worst case
condition(4.75Vsupplyand13Vsignallevel).
The tolerances in the design guarantee detection of the above
levels, so the actual acceptance ranges are slightly larger. If the
ARINC signal is out of the actual acceptance ranges, including the
nulls,thechiprejectsthedata.
