Hello team,
About DS90UB913/914, my camera data isn't correctly sent. Could you please help me to address this issue?
Please find my waveform from the internal link here.
The image sensor PCLK is designed at 96MHz.
When the serdes is communicating, the PCLK of deserializer breaks up as shown in waveform #2.
The jitter spec of the image sensor is 600ps, so I don't think the jitter should be the cause.
My customer has experience that the serdes worked with VDDIO=3.3V in another application.
In this use case, VDDIO is 1.8V. My customer set 0x01[4] as 0 to set to 1.8V mode, but the problem was not solved.
Is there any missing register setting specifically for VDDIO=1.8V?
Also, My customer realized that the deseralizer's PLL is locking. Could you please let me know the possible cause of the PLL locking?
Regards,
Itoh
