DS90UB927Q-Q1: Image distortion during customer's test

Part Number: DS90UB927Q-Q1

Hello team,

My customer has a test issue during the reliability test and has some questions about the serializer (DS90UB927QSQ / NOPB).

The details include customer's project information, so if you couldn't find out what may be the problem from this information alone, I would like to contact you directly by email.

★ Problem
-The DS90UB927QSQ / NOPB mounting unit has a problem that the image is distorted during the reliability test. (Please refer to the attached Excel for details)

★ Questions
(1) Since the color bar can be output in the test mode built into the device, it is estimated that there is a problem with the LVDS input / output.
Please comment on the possibility that the DS90UB927QSQ / NOPB may malfunction under the test conditions like this time (especially the LVDS input part).

(2) Please let us know if there are any other possible causes for the following image distortion.

I'm looking forward to hearing from you.

Best Regards,

Ryotaro Fukui
