RECEIVER LOGICOPERATION
BIT TIMING
Figure 2 shows a block diagram of the logic section of each
receiver.
The ARINC 429 specification contains the following timing
specification for the received data:
100K BPS ± 1% 12K -14.5K BPS
1.5 ± 0.5 μsec
1.5 ± 0.5 μsec
5 μsec ± 5%
10 ± 5 μsec
10 ± 5 μsec
34.5 to 41.7 μsec

RECEIVER PARITY
The receiver parity circuit counts Ones received, including the
parity bit, ARINC bit 32. If the result is odd, then "0" will appear in
the 32nd bit.
Once 32 valid bits are recognized, the receiver logic generates an
End of Sequence (EOS). If the receiver decoder is enabled and
the 9th and 10th ARINC bits match the control word program bits
or if the receiver decoder is disabled, then EOS clocks the data

INTERNAL LIGHTNING PROTECTION (-10 Only)
APPLICATION NOTE 300
The HI-3282-10 configurations are similar to the HI-3282 except
that the ARINC inputs are internally lightning protected to
DO-160D, Level 3 through 10 Kohm resistors that
connected in series with each input from theARINC bus.
be
The design of the HI-3282-10 device requires the external
10 Kohm series resistors for proper ARINC level detection. The
typical 10 volt differential signal is translated and input to a
window comparator and latch. The comparator levels are set so
that, with the external 10 Kohm resistors, they are just below the
standard 6.5 V minimum ARINC data threshold and just above the
2.5 V maximumARINC null threshold.
The receivers of the HI-3282-10 when used with external 10
Kohm resistors will withstand DO-160D, Level 3, waveforms 3, 4
and 5A. No additional lightning protection circuit is necessary.
Please refer to the Holt AN-300 Application Note for additional
information and recommendations on lightning protection of Holt
Line Drivers and Receivers.
