TIDA-01536: TIDA-01536

Part Number: TIDA-01536
Other Parts Discussed in Thread: XTR111

We are having some issues with XTR111 susceptibility to external noise. For example, when we perform the IEC61000-4-6: Conducted Immunity test, we are measuring up to 8Vpp noise on a 10V signal. Based on the reference design testing:

http://www.ti.com/lit/ug/tidub12/tidub12.pdf

we should be seeing something like 0.2% which is significantly lower than what we are measuring. To better understand this, can you help us with the following:

- request test details (ie. where and how did they apply the conducted emissions)

- can we get our hands on the reference design board (can't find it anywhere)?

Hi Chris,

Our apps engineer that supports this is traveling right now. I will seek clarification from him and get back to you as soon as I can. I do not believe that EVM is order-able, but I can check. In addition, the conducted immunity test can be dependent on many factors, especially layout. Would be possible for you to share your layout and schematic? If you do not want to share it on e2e, you are welcome to email it to me at frost@ti.com.

Thanks,
Paul

Hi Chris,

Can you go into some detail about your test configuration? TI has published this application note which applies to IEC61000-4-6, and has some notes about the 4-6 test.
