Railway information

Block diagram

Overview

Our integrated circuits and reference designs help you create reliable, safe and automated railway information systems for passengers. Using our innovative technology, you can develop human machine interface (HMI) with high audio/video performance and run multi-protocol train communication interfaces.

Design requirements

Railway information systems often require:

  • Powerful processing for graphic displays and various digital multimedia.
  • Efficient power-tree design to support multiple input power sources.
  • High performance audio interface to transmit signals without distortion.
  • Robust multiprotocol communication interfaces for highly-reliable interconnect.
