DS90UB962-Q1: ECC Error

Part Number: DS90UB962-Q1

Is there a testing method that can reproduce ECC Error? For example, constantly switching video streams? Or ECC errors caused by hardware LINK disconnection/connection?

Because the customer hopes to have a reproducible ECC error method on the test bench, and then use improved software strategies to prove its effectiveness.

The customer attempted to reproduce ECC errors by manually switching video streams on the testing bench last weekend But after testing for two days, I couldn't reproduce it.

Do you have any other suggestions Because the customer requested to reproduce the problem and use our improved software to see if it can be completely avoided

  • Hi Ray,

    Are you referring to ECC errors on the CSI-2 packet header? Specific CSI-2 packet errors cannot be forced in our devices since our devices simply pass through CSI-2 packets while detecting errors. However, you can run the serializer and deserializer in BIST mode and program the serializer to force an error on the forward channel (see 953 register 0x14). More information about this feature is in the BIST sections of the datasheets.

    Regards,
