Holt HI-8589PJT-10 Arinc 429 line driver and dual receiver Datasheet

HI-8581, HI-8589
ARINC 429 LINE DRIVER AND DUAL RECEIVER
FEATURES
The HI-8581 and HI-8589 from Holt Integrated Circuits are
silicon gate CMOS devices for interfacing a 16-bit parallel
data bus directly to the ARINC 429 serial bus. Both
devices provide two receivers, an independent transmitter
and line driver capability in a single package. The receiver
input circuitry and logic are designed to meet the
ARINC 429 specifications for loading, level detection,
timing, and protocol. The transmitter section provides the
ARINC 429 communication protocol and the line driver
circuits provide the ARINC 429 output 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.
The HI-8581 has 37.5 ohms in series with each line driver
output. The HI-8589 provides the option to bypass most of
the internal output resistance so that external series
resistance may be added for lighting protection and still
match the 75 ohm characteristic impedance of the ARINC
bus.
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 HI-8581 and HI-8589 examine the null and data
timings and will reject erroneous patterns. For example,
with a 125 KHz clock selection, the data frequency must
be between 10.4 KHz and 15.6 KHz.

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 RECEIVERS
ARINC BUS INTERFACE
Figure 1 shows the input circuit for each receiver. The ARINC 429
specification requires the following detection levels:
STATE
ONE
NULL
ZERO
DIFFERENTIAL VOLTAGE
+6.5 Volts to +13 Volts
+2.5 Volts to -2.5 Volts
-6.5 Volts to -13 Volts
The HI-8581 and HI-8589 guarantee recognition of these levels with
a common mode Voltage with respect to GND less than ±4V for the
worst case condition (4.75V supply and 13V signal level).
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, the chip rejects the data.

FUNCTIONAL DESCRIPTION (cont.)
RECEIVER LOGIC OPERATION
3. Each data bit must follow its predecessor by not less than
8 samples and no more than 12 samples. In this manner the
bit rate is checked. With exactly 1MHz input clock frequency,
the acceptable data bit rates are as follows:
Figure 2 shows a block diagram of the logic section of each receiver.
BIT TIMING
DATA BIT RATE MIN
DATA BIT RATE MAX
The ARINC 429 specification contains the following timing specification for the received data:
HIGH SPEED
LOW SPEED
100K BPS ± 1% 12K -14.5K BPS
BIT RATE
10 ± 5 µsec
PULSE RISE TIME 1.5 ± 0.5 µsec
10 ± 5 µsec
PULSE FALL TIME 1.5 ± 0.5 µsec
5 µsec ± 5%
34.5 to 41.7 µsec
PULSE WIDTH
The HI-8581 and HI-8589 accept signals that meet these specifications and rejects outside the tolerances. The way the logic operation achieves this is described below:
1. Key to the performance of the timing checking logic is an accurate 1MHz clock source. Less than 0.1% error is recommended.
2. The sampling shift registers are 10 bits long and must show
three consecutive Ones, Zeros or Nulls to be considered valid
data. Additionally, for data bits, the One or Zero in the upper
bits of the sampling shift registers must be followed by a Null in
the lower bits within the data bit time. For a Null in the word
gap, three consecutive Nulls must be found in both the upper
and lower bits of the sampling shift register. In this manner the
minimum pulse width is guaranteed.
HIGH SPEED
LOW SPEED
83K BPS
125K BPS
10.4K BPS
15.6K BPS
4. The Word Gap timer samples the Null shift register every
10 input clocks (80 for low speed) after the last data bit of a
valid reception. If the Null is present, the Word Gap counter
is incremented. A count of 3 will enable the next reception.
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.
RETRIEVING DATA
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 ready flag flip flop to a "1", D/R1 or D/R2 (or both) will go
low. The data flag for a receiver will remain low until after both
ARINC bytes from that receiver are retrieved. This is accomplished by first activating EN with SEL, the byte selector, low to
retrieve the first byte and then activating EN with SEL high to retrieve the second byte. EN1 retrieves data from receiver 1 and
EN2 retrieves data from receiver 2.
If another ARINC word is received and a new EOS occurs before
the two bytes are retrieved, the data is overwritten by the new
word.

FUNCTIONAL DESCRIPTION (cont.)
TRANSMITTER PARITY
TRANSMITTER
The parity generator counts the ONES in the 31-bit word. If the
BD12 control word bit is set low, the 32nd bit transmitted will
make parity odd. If the control bit is high, the parity is even.
A block diagram of the transmitter section is shown in Figure 3.
SELF TEST
FIFO OPERATION
If the BD05 control word bit is set low, the digital outputs of the
transmitter are internally connected to the logic inputs of the
receivers, bypassing the analog bus interface circuitry. Data to
Receiver 1 is as transmitted and data to Receiver 2 is the
complement. All data transmitted during self test is also present
on the TXA(OUT) and TXB(OUT) line driver outputs.
The FIFO is loaded sequentially by first pulsing PL1 to load byte 1
and then PL2 to load byte 2. The control logic automatically loads
the 31 bit word in the next available position of the FIFO. If TX/R,
the transmitter ready flag is high (FIFO empty), then 8 words,
each 31 bits long, may be loaded. If TX/R is low, then only the
available positions may be loaded. If all 8 positions are full, the
FIFO ignores further attempts to load data.
SYSTEM OPERATION
DATA TRANSMISSION
The two receivers are independent of the transmitter. Therefore,
control of data exchanges is strictly at the option of the user. The
only restrictions are:
When ENTX goes high, enabling transmission, the FIFO
positions are incremented with the top register loading into the
data transmission shift register. Within 2.5 data clocks the first
data bit appears at either TXA(OUT) or TXB(OUT). The 31 bits in
the data transmission shift register are presented sequentially to
the outputs in the ARINC 429 format with the following timing:
ARINC DATA BIT TIME
DATA BIT TIME
NULL BIT TIME
WORD GAP TIME
HIGH SPEED
10 Clocks
5 Clocks
5 Clocks
40 Clocks
1. The received data may be overwritten if not retrieved
within one ARINC word cycle.
2. The FIFO can store 8 words maximum and ignores
attempts to load addition data if full.
LOW SPEED
80 Clocks
40 Clocks
40 Clocks
320 Clocks
3. Byte 1 of the transmitter data must be loaded first.
4. Either byte of the received data may be retrieved first.
Both bytes must be retrieved to clear the data ready flag.
The word counter detects when all loaded positions are
transmitted and sets the transmitter ready flag, TX/R, high.
5. After ENTX, transmission enable, goes high it cannot go
low until TX/R, transmitter ready flag, goes high. Otherwise,
one ARINC word is lost during transmission.

FUNCTIONAL DESCRIPTION (cont.)
HI-8581-10 and HI-8589-10
LINE DRIVER OPERATION
The “-10” versions of the HI-8581 and HI-8589 products require a
10 Kohm resistor to be placed in series with each ARINC input
without affecting the ARINC input thresholds. This option is
especially useful in applications where external lightning
protection is required.
The line driver in the HI-8581 and HI-8589 is designed to directly
drive the ARINC 429 bus. The two ARINC outputs (TXA(OUT) and
TXB(OUT)) provide a differential voltage to produce a +10 volt
One, a -10 volt Zero, and a 0 volt Null. Setting Control Register bit
13 to zero causes a slope of 1.5 ms on the ARINC outputs. A one in
Control Register bit 13 causes a slope of 10 ms. Timing is set by onchip resistor and capacitor and tested to be within ARINC requirements. No additional hardware is required to control the slope. The
HI-8581 has 37.5 ohms whereas the HI-8589 has 10 ohms in
series with each line driver output. The HI-8589 is for applications
where additional external series resistance is required, such as
lightning protection.
Each ARINC input pin must be connected to the ARINC bus
through a 10 Kohm resistor in order for the chip to properly detect
the correct ARINC levels. 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 volt minimum
ARINC data threshold and just above the 2.5 volt maximum
ARINC null threshold.
REPEATER OPERATION
Please refer to the Holt AN-300 Application Note for additional
information and recommendations on lightning protection of Holt
line drivers and line receivers.
Repeater mode of operation allows a data word that has been
received by the HI-8581 or HI-8589 to be placed directly into its
FIFO for transmission. Repeater operation is similar to normal
receiver operation. In normal operation, either byte of a received
data word may be read from the receiver latches first by use of SEL
input. During repeater operation however, the lower byte of the
data word must be read first. This is necessary because, as the
data is being read, it is also being loaded into the FIFO and the
transmitter FIFO is always loaded with the lower byte of the data
word first. Signal flow for repeater operation is shown in the
Timing Diagrams section.
POWER SUPPLY SEQUENCING
The power supplies should be controlled to prevent large currents
during supply turn-on and turn-off. The recommended sequence
is V+ followed by Vcc, always ensuring that V+ is the most
positive supply. The V- supply is not critical and can be asserted
at any time.
MASTER RESET (MR)
On a Master Reset data transmission and reception are
immediately terminated, all three FIFOs are cleared as are the
FIFO flags at the device pins and in the Status Register. The
Control Register is not affected by a Master Reset.
