Having studied the following documents:
AN-0971 - Recommendations for Control of Radiated Emissions with isoPower Devices and
AN-1109 - Recommendations for Control of Radiated Emissions with iCoupler Devices
can i make the conclusion that using both series on a normal dual-layer PCB (FR4) is guaranteed to fail the radiated emmisions requirements (Board only, no housing).
Does Analog Device have other application notes / test reports on how these units can be used on dual layer PCBs and the best way they can be used and what the restrictions may be. Like: isoPower at 3V3-10mA with 100kps and board x would pass if y and z are met?
The isoPower and iCoupler series look very nice but converting some existing dual layer boards (with opo+power) to 4-layer boards would cost to much and has no other advantages (in our case).
