Recommendations for Control of Radiated Emissions with iCoupler Devices  
by Brian Kennedy and Mark Cantrell  
addressing them through high frequency PCB design  
techniques.  
INTRODUCTION  
iCoupler® data isolation products can readily meet CISPR 22  
Class A (and FCC Class A) emissions standards, as well as the  
more stringent CISPR 22 Class B (and FCC Class B) standards in  
an unshielded environment, with proper PCB design choices.  
This application note examines PCB-related EMI mitigation  
techniques, including board layout and stack-up issues.  
Control of emissions from signal cables and chassis shielding  
techniques are outside of the scope of this application note.  
EMI MITIGATION OVERVIEW  
Best-practice techniques for EMI mitigation include a  
combination of the use of input-to-output ground plane  
stitching capacitance, edge guarding, and the reduction of  
supply voltage levels for noise reduction. For the purposes  
of this application note, a 4-layer board was designed and  
manufactured using materials and structures well within  
industry practice.  
Several standards for radiated emissions exist. In the U.S., the  
Federal Communications Commission (FCC) controls the  
standards and test methods. In Europe, the International  
Electrotechnical Commission (IEC) generates standards, and  
CISPR test methods are used for evaluating emissions. The  
methods and pass/fail limits are slightly different under the two  
standards. Although this application note references IEC stand-  
ards, all results are applicable to both standards.  
The EMI reduction examples used in this application note are  
based on the 4-channel iCoupler products, but the information  
is relevant to all the iCoupler product families, examples of which  
are shown in Figure 1.  
Data transitions at the input of iCoupler digital isolators are  
encoded as narrow pulses that are used to send information  
across the isolation barrier. These 1 ns pulses have peak  
currents of up to 70 mA and may cause radiated emissions and  
conducted noise if not considered during printed circuit board  
(PCB) layout and construction. This application note identifies  
the radiation mechanisms and offers specific guidance on  
For information on reducing emissions from products using  
isoPower, integrated isolated power, refer to the AN-0971  
Application Note, which includes additional recommendations  
and techniques.
