HI-1569 August 2006 MIL-STD-1553 / 1760 5V Monolithic Dual Transceiver FEATURES DESCRIPTION The HI-1569 is a low power CMOS dual transceiver designed to meet the requirements of MIL-STD-1553 /1760 specifications. The transmitter section of each channel takes complementary CMOS / TTL digital input data and converts it to bi-phase Manchester encoded 1553 signals suitable for driving the bus isolation transformer. Separate transmitter inhibit control signals are provided for each transmitter. The receiver section of each channel converts the 1553 bus bi-phase data to complementary CMOS / TTL data suitable for inputting to a Manchester decoder. Each receiver has a separate enable input which can be used to force the output of the receiver to a logic 0. The transmitter outputs and receiver inputs for each channel are brought out to separate sets of pins. For typical MIL-STD-1553 applications the transmitter output and receiver input will be tied together at the isolation transformer. ! Compliant to MIL-STD-1553A & B, MIL-STD-1760, ARINC 708A !

May be left open or connected to power or ground FUNCTIONAL DESCRIPTION The HI-1569 data bus transceiver contains differential voltage source drivers and differential receivers. It is intended for applications using a MIL-STD-1553 A/B data bus. The device produces a trapezoidal output waveform during transmission. TRANSMITTER Data input to the device’s transmitter section is from the complementary CMOS /TTL inputs TXA/B and TXA/B. The transmitter accepts Manchester II bi-phase data and converts it to differential voltages on BUSA/B OUT and BUSA/B OUT. The transceiver outputs are either direct or transformer coupled to the MIL-STD-1553 data bus. Both coupling methods produce a nominal voltage on the bus of 7.5 volts peak to peak. The transmitter is automatically inhibited and placed in the high impedance state when both TXA/B and TXA/B are either at a logic “1” or logic “0” simultaneously. A logic “1” applied to the TXINHA/B input will force the transmitter to the high impedance state, regardless of the state of TXA/B and TXA/B. RECEIVER The receiver accepts bi-phase differential data from the MILSTD-1553 bus through a direct or transformer coupled interface. The receiver’s differential input stage drives a filter and threshold comparator that produces CMOS/TTL data at the RXA/B and RXA/B output pins. Each set of receiver outputs can be independently forced to a logic "0" by setting RXENA or RXENB low. MIL-STD-1553 BUS INTERFACE A direct coupled interface (see Figure 2) uses a 1:2.5 ratio isolation transformer and two 55 ohm isolation resistors between the transformer and the bus. In a transformer coupled interface (see Figure 3), the transceiver is connected to a 1:1.79 isolation transformer which in turn is connected to a 1:1.4 coupling transformer. The transformer coupled method also requires two coupling resistors equal to 75% of the bus characteristic impedence (Zo) between the coupling transformer and the bus.
