HI-8282 September 2006 ARINC 429 SERIAL TRANSMITTER AND DUAL RECEIVER FEATURES ! ARINC specification 429 compliant ! 16-Bit parallel data bus ! Direct receiver interface to ARINC bus ! Timing control 10 times the data rate ! Selectable data clocks ! Receiver error rejection per ARINC specification 429 ! Automatic transmitter data timing ! Self test mode ! Parity functions ! Low power, single 5 volt supply ! Industrial & full military temperature ranges GENERAL DESCRIPTION The HI-8282 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 transmitter section provides the ARINC 429 communication protocol. An external line driver such as the Holt HI-8585 or HI-3182 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 HI-8282 examines 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. !

Each flip flop provides options to the user as follows: DATA BUS ARINC 429 DATA FORMAT The following table shows the bit positions in exchanging data with the receiver or the transmitter.

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.

ARINC RECEIVER INPUT HOLT INTEGRATED CIRCUITS 3 HI-8282 FUNCTIONAL DESCRIPTION (cont.) RECEIVER LOGIC OPERATION Figure 2 shows a block diagram of the logic section of each receiver. BIT TIMING 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-8282 accepts 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. 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: HIGH SPEED DATA BIT RATE MIN DATA BIT RATE MAX 83K BPS 125K BPS LOW SPEED 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 activating EN with SEL, the byte selector, low to retrieve the first byte and 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.

RECEIVER BLOCK DIAGRAM HOLT INTEGRATED CIRCUITS 4 HI-8282 FUNCTIONAL DESCRIPTION (cont.) TRANSMITTER A block diagram of the transmitter section is shown in Figure 3. TRANSMITTER PARITY 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. FIFO OPERATION 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. SELF TEST 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. SYSTEM OPERATION 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: 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. 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. 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. BIT BD12 DATA TRANSMISSION 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 429DO or 429DO. The 31 bits in the data transmission shift register are presented sequentially to the outputs in the ARINC 429 format with the following timing: HIGH SPEED 10 Clocks 5 Clocks 5 Clocks 40 Clocks LOW SPEED 80 Clocks 40 Clocks 40 Clocks 320 Clocks ARINC DATA BIT TIME DATA BIT TIME NULL BIT TIME WORD GAP TIME The word counter detects when all loaded positions are transmitted and sets the transmitter ready flag, TX/R, high. 31 BIT PARALLEL LOAD SHIFT REGISTER BIT CLOCK PARITY GENERATOR DATA AND NULL TIMER SEQUENCER 429DO 429DO WORD CLOCK BIT AND WORD GAP COUNTER START SEQUENCE 8 X 31 FIFO ADDRESS LOAD WORD COUNTER AND FIFO CONTROL INCREMENT WORD COUNT TX/R ENTX FIFO LOADING SEQUENCER PL1 PL2 DATA BUS DATA CLOCK DATA CLOCK DIVIDER CLK TX CLK FIGURE 3. TRANSMITTER BLOCK DIAGRAM CONTROL BIT BD13 HOLT INTEGRATED CIRCUITS 5 HI-8282 FUNCTIONAL DESCRIPTION (cont.) REPEATER OPERATION he repeater mode of operation allows a data word that has been received by the HI-8282 to be placed directly into its FIFO for transmission. After a 32-bit word has been shifted into Tthe receiver shift register, the D/R flag will go low. A logic "0" is placed on the SEL line and EN is strobed. This is the same procedure as for normal receiver operation and it places the lower byte (16) of the data word on the data bus. By strobing PL1 at the same time as EN , the byte will also be placed into the transmitter FIFO. SEL is then taken high and EN is strobed again to place the upper byte of the data word on the data bus. By strobing PL2 at the same time as EN, the second byte will also be placed into the FIFO. The data word is now ready to be transmitted according to the parity programmed into the control word register. 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. 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.
