Part Number: DS90UB948-Q1

Hello TI Experts,

I am now using DS90UB948,and have a problem need your help:

Can I put a common mode inductance desides 100Ω to improve EMC?

Do I need to add common mode inductance in the input signal of DS90UB948 to improve EMC?

hi Thank you very much for your information~
So common mode inductance in the output side is not necessary but can be allowed?

Yes. It is tradeoff between ESD protection and SI performance.
