When we use the retimer to drive camera MIPI signal, the DB output will have peak as the capture shows:but when camera sensor connect to SOC directly, it does not have .
When the HS exit to LP,the THS-skip window has a bit flip.
Are they caused by the IC design bug or the design principle ?
Hi,
The scope waveform looks to be single ended measurement, can you do a differential measurement? There is a dip at the DPHY440 input as shown below. Depends on the threshold of the dip, I wonder if the dip would be seen by the DPHY440 as a valid switching and this is why you saw the bit flip at the output.
For the peak issue, are you seeing any functional issue?
Thanks
David
