Part Number: DS90UB638-Q1

I've confgiured the DS90UB638-Q1 de-serializer in the internal pattern generation mode. I've probed the data lines on oscilloscope. Kindshared image (2).jpgly see if the pattern generation signal is valid/invalid.

    Hello Abhijit,

    It does look like there is data being sent on the CSI data lanes, but there is no way to check its validity (data contents) based on just this screenshot. You would need to hook up the CSI output to some sort of CSI analyzer or processor to display the CSI output.

    You can compare your data lane outputs to the oscilloscope screenshots in Section 8.2.3 Application Curves in the 936/954 datasheets as well.

    Best,
