MISSION VIEJO, Calif. – Holt Integrated Circuits in Mission Viejo, Calif., is introducing the HI-15850 3.3-volt MIL-STD-1553 dual transceiver for commercial and military avionics databus applications.
The HI-15850 offers 1.8-, 2.5-, and 3.3-volt compatible digital I/O to provide systems designers with flexibility to interface with a broad range of field-programmable gate arrays (FPGAs) and avoid use of level shifters and other additional circuitry.
This device is based on Holt's HI-1585 and provides the same features of bus tail-off compensation and receiver output pulse extension. Tail-off compensation compensates for bus tail-off, which is an undesirable temporary DC offset on the terminal's bus stub.
The avionics databus receiver output pulse extension ensures receiver output pulse widths remain above 180 nanoseconds, improving receiver sensitivity for designs operating close to the minimum receiver input response amplitude and ensuring proper decoding.
"This device will enable customers to use their existing FPGA digital I/O without the need for voltage conversion or other logic," explains George Noh, director of sales and marketing at Holt.
The HI-15850 comes in a 48-pin plastic 6-by-6-millimeter QFN package with an exposed heat sink pad, which may be soldered to the circuit board ground plane for optimal thermal dissipation.
The transceiver is available in versions that operate in the industrial temperature range of -40 to 85 degrees Celsius, and in the military temperature range of -55 to -125 C. Optional burn-in available on the military-temperature device.
