Require isolators for medical device, compliant with IEC60601-1-2-26, the emi/rfi section of the 60601-1 general spec.
FDA require emissions below CISPA 11, class 1, Level 2 for IEC60601-1 class 1 configured device, i.e. metal/conductive enclosure attached to safety earth ground.
What is the radiated emissions for the Si8824x, Vin = 5V?
Data as in Fig 3 of "Low emi isolation for medical equipment applications" for the 8824x to compare to the limits set by CISPR11.
Is there a document specifically making recommendations for the 8824X minimizing emissions extending beyond AN583: Safety Considerations and Layout Recommendations for Digital Isolators?
and in save philosophy as TI
Lastly, are there other components at Vin and Vout fig1 of AN892 recommended to minimize radiation?
I will reply on your SalesForce ticket rather than here.
