HI-3718
3.3V single supply operation. Harvard Bi-Phase (HBP) and Bi-Polar Return-to-Zero (BPRZ) line receiver and line drivers.
3.3V ARINC 717 / ARINC 429 Transceiver
The HI-3718 is a low-power CMOS transceiver designed to meet the requirements of the ARINC 717 and ARINC 429 specifications. The device acts as an interface between ARINC 717 or ARINC 429 digital protocols and the Harvard Bi-Phase (HBP) and/or Bi-Polar Return-toZero (BPRZ) encoded physical layers.
The part includes a Harvard Bi-Phase (HBP) or Bi-Polar Return-to-Zero (BPRZ) line receiver which produces correct HBP or BPRZ digital signals for input to a decoder. The device also has HBP and BPRZ line drivers capable of accepting HBP and BPRZ-encoded digital signals. The device operates from a single +3.3V supply using only four external capacitors, making it the ideal interface device between an FPGA and ARINC 717 physical layer. The HI-3718 is available in very small 32-pin 7mm x 7mm chip-scale (QFN) and 32-pin Quad Flat Pack (PQFP) plastic packages.
