Hello Guys,
Good day.
Our customer got the DS90UB960EVM and is having issues with the CSI-2 output. He connected a Camera with a serializer DS90UB953 and manage to get the video stream at the output pins of the deser board, But when he check the CSI clock lane, it seems that no clock is transferred.
When he look at the CSI output at oscilloscope, he can recognize LP11, LP01, LP00 zones but the csi clock should arrive right after that like in page-153 of the deserializer datasheet.
To be more precise, the data lanes seems to be perfect but only the clock lane seems strange. After the LP11, LP01 and LP00 zones, the clock lane is stuck at 250mV without any changes. When he check at p153 of deserializer datasheet, he got the same but not for the clock lane which stay constant.
Thanks in advance.
