iGU – Instrumentation Gateway

Highlights

  • PCM Inputs/Outputs, NTSC Video Input
  • IEEE-1588v2 Master/Slave, IRIG TCG
  • PCM & Video to Chapter 10 UDP
  • Ethernet/Chapter 10 UDP to HDLC/Chapter 7 PCM
  • Ethernet/DAR & HDLC/Chapter 7 PCM

Overview
The iGU is a configurable gateway between instrumentation systems and Ethernet networks or telemetry transmitters. Currently used with-in the Common Airborne Network Instrumentation System (CANIS) project.

This small self-contained rugged airborne unit, contains a layer 2/3 managed Ethernet switch, powerful FPGA and quad-core ARM CPU which allows unprecedented flexibility in data processing and protocol transforms.

Along with PCM and video inputs/outputs the iGU also contains a hardware based IEEE-1588v2 time engine with in the switch and a 1PPS output from the 1588 time.
