Routing & transport systems for broadcast

Block diagram

Overview

Our integrated circuits and reference designs help you create routing and transport systems for broadcast. Whether you need to design hundreds of channels of video routers or various channels of audio switchers, we have the right ingredients and solutions.

Design requirements

Routing and transport systems for broadcast designs often require:

  • Auto signal detection and conditioning to simplify system design.
  • Comprehensive portfolio of SDI/ASI/AES solutions.
  • Outstanding maintainability and redundancy to enable 24/7 application continuity.
  • High-power density and efficiency for larger scale routing systems.
