DS90UB953-Q1: FPD-LINK III driver specifications during EMC test

Chase Jeong

Part Number: DS90UB953-Q1

Hello TI experts,

My customer considers DS90UB953 for their new product, and they need some specifications to make final document with their client.

-> “N” being nominal, what is typical without disturbances.

-> “A” being an acceptable value observed during a disturbance or deviation during testing(EMC).

575mVp-p

20Mhz ~ 2.1Ghz

they wrote 575mVp-p from the datasheet below;

and my question is, do you have any specific value for the question marks with yellow highlighted in the table?

Please check this issue. Thanks.

Hi Chase,

I am not sure I understand your questions here. During a disturbance you want to know what the output might be?

Hi Nick,

Thank you for your support.

You are right, Is there any specified value about the output (voltage, frequency, etc) during disturbance like EMC, ESD or something?

Best regards,

Chase

Hi Chase,

I don't that this would be something that we would be able to spec? What constitutes a disturbance and how would you quantify the intensity of the disturbance? During an immunity test any number of things may happen which is why good board design and grounding is required. On the product page we have some information regarding design and setup tips for conducting EMC testing if that would help.

Regards,

Nick
