HI-1587

The HI-1587 is an ultra-low power MIL-STD-1553 dual transceiver designed to meet all requirements of the MIL-STD-1553 and MIL-STD-1760 specifications. The device is designed to provide the transceiver interface between the bus isolation transformers and an FPGA with instantiated Holt MIL-STD-1553 IP Core and features an integrated IP security module necessary to enable the IP. This eliminates the need for a traditional external IP dongle chip, commonly used with other IP solutions.

The HI-1587 is also the first MIL-STD-1553 transceiver to feature 1.8V, 2.5V and 3.3V compatible digital I/O, making it easier to interface with a broad range of FPGAs.

The transmitter takes complementary CMOS / TTL Manchester II bi-phase data and converts it to differential voltages suitable for driving the bus isolation transformer. Separate transmitter inhibit control signals are provided for each bus. The receiver section of the each bus converts the 1553 bus bi-phase analog signals to complementary CMOS / TTL data suitable for input to the IP Core Manchester decoder.

The device is packaged in the industries smallest MIL-STD-1553 transceiver package, a 48-pin plastic 6mm x 6mm QFN with an exposed heat sink pad, which may be soldered to the PCB ground plane for optimal thermal dissipation. The device is available in industrial −40oC to +85oC and extended −55oC to +125oC temperatures, with optional burn-in available on the extended temperature range.
