Hi, team:
My customer has a multi-camera image stitching project. If you supply power to the serializer separately, it can add serial/deserial strings normally. If use POC to supply power, the LOCK signal will change continuously.
Observe the POC filter output voltage, it is stable (no obvious drop). And the eye diagram of the FPD-LINK signal is basically the same as when the deserialization is normal.(no template, only two eye diagrams can be compared).
What are the reasons for this phenomenon?
