DS90UB936-Q1: DS90UB936 screen jitter or flashing lines

Zheng Yang

Part Number: DS90UB936-Q1

Hi TI team:

We used the DS90UB936 deserializer, and found that some machines had screen jitter or flashing lines. After analysis, the DS90UB936 on the jitter or flashing machine was exchanged with the DS90UB936 on the normal machine, and it was found that the failure phenomenon followed DS90UB936. what is the reason? Is there a problem with DS90UB936? Or 936 which register is configured incorrectly? See the attached video for details of the fault phenomenon.

thks!

Hello， there is a similar post which is about the flicker issue: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1024445/ds90ub936-q1-flickering-issue

And I also asked the same questions about UB936 which works abnormally, does the LOCK pin temporarily drop on the 936 side? Does the 936 report any errors in the register related to the FPD-Link or the CSI-2?
