Certified Electromagnetic Compatible RS-485 Interface Design Tool

#1 Design Challenge for Industrial Communications Ports is Meeting EMC requirements. 

Combining Industry Leading Analog Devices RS-485 and Bourns external protection expertise solves EMC problems for RS-485 comms ports.

EMC Design Challenge

  • Achieving compliance to EMC Regulations
  • Difficult to match the dynamic breakdown characteristics of
    • The protected device IO
    • And the protection components
  • Time to Market:
    • Multiple Board iterations
    • Budget Overruns


ADI/BOURNS Solution

Certified* EMC Compliant RS485 Interface Design Tool

  • Saves time and budget by allowing:
    • Testing of the circuits at the beginning of the design cycle.
    • Use of schematics and layout as a starting point in your design.

Product Details

The ezLINX™ iCoupler® Isolated Interface Development Environment provides developers with a cost-effective, plug and play method for evaluation eight physical layer, digitally-isolated communication standards (USB, RS-422, RS-485, RS-232, CAN, SPI, I2C, and LVDS). The Blackfin® ADSP-BF548 processor is used to run the uCLinux operating system and allows for easy customization through the open source hardware and software platform. Development time is significantly reduced for embedded designers and system architects who are designing and evaluating isolated communication standards. The interfaces on ezLINX use ADI's isolated transceivers with integrated iCoupler® and isoPower® digital isolator technology.
