DS90UB954-Q1: How to debug image issue

Part Number: DS90UB954-Q1

Hi Champs,

My customer tested with Sensor + DS90UB953 + DS90UB954 + ISP setup and having issue on ISP output image.

Please check attached file including Hardware setup, register setup, and images with issue.

Have you seen this kind of problem with 953 + 954 setup?

Could you advice how to debug and identify cause for this issue?

Any comment or advice would be quite helpful.

Best regards,

    Hi Fujihara-san,

    I recommend setting your reg 0x58 to 0x5E instead.

    Can you check if you are getting any ECC or checksum errors (reg 0x7A from 954)? If not, I suspect the problem you are seeing is from the imager itself.

    Best,
