DescriptionThe 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/ TTLdigital input data and converts HI-1569 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 HI-1569 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.
HI-1569
Holt Integrated Circuits, the leader in ARINC 429 components, has continued its commitment to MIL-STD-1553 with their HI-1569 transceiver. Using proven design techniques and state-of-the-art analog CMOS technology, the new HI-1569 is the most robust and power-efficient 5V dual tranceiver in the industry. The device provides separate transmitter outputs and receiver input pins for each of the two independent channels.
The HI-1569 is available in a small 64-pin plastic quad flat pack (PQFP) package. Measuring 0.63 inches square, and only 0.063 inches thick, the HI-1569 is well suited for applications where size is a consideration.
Like the Holt HI-1567 and HI-1568, the HI-1569 offers users a lower-cost, lower-power replacement for 64-pin QFP transceivers from other manufacturers.
Samples of the HI-1569 are readily available. The part may be used with standard MIL-STD-1553 transformers with a 1:2.5 turns ratio for direct coupled and 1:1.79/1:1.4 turns ratios for transformer coupled bus connections.
