Dear expert,
Customer face to mismatch failed of MIPI_CSI HSTX.
According to our datasheet, the maximum value is 14mV when output 0/1.
Did we have register can fine tune this error? Thanks.
Regards,
Ben

Ben,
For UB954's CSI2 port, the DPHY spec. is verified to pass the 3rd party MIPI compliance test. For this mismatch spec. that you listed here, sorry we can't find tune it. But I would like to check the compliance test setup in your system when issue is reported.
best regards,

Hi Junqiang,
Thanks for your support.
Customer still face to MIPI VOD mismatch issue now.
They have add 1pF at CSI_D0N and improve test result to close to margin.
As your last comment, we don't have register to fine-tune it. Is there any risk we add capacitor at CSI_D0N?
Attachment are last compliance test report I get from customer. please refer to this report.

I am asking for customer about the setup of compliance test with zoom in and point at device location.
Will share with you once I get.
