Part Number: DS90UR903Q-Q1 We are using one of the 21 input pins as HOT_SWAP and notice voltage rails 1.8V shorting to VDDIO 3.3V. I suspect the internal MOSFET not sized for hot-swap application. See the attachment on internals in the functional block…

This is a legacy device, how old is this application? Around 6 years old, but it may have been carried over from a predecessor product which goes…
Part Number: DS90UR903Q-Q1 Description of the issue:
We have had several field failures of the serializer (PN: DS90UR903QSQE/NOPB), where the 1.8V power is shorting to 3.3V power inside the chip after failure. When the boards are diagnosed, all devices…

Part Number: DS90UR903Q-Q1 Hi Team,
I have a question.
Can DS90UR903Q and DS90UB904Q be connected? I think I can not connect.
Because UR DS90UR903Q is FPD-Link2. DS90UB904Q is FPD-Link3. I can not connect because the generation of IF is different…

Hi,
On the customer's board the symptom not outputting signal occurs sometimes(once a 20~30 times) as attached.
DS90UR903-Q1.xlsx
Power supply and PCLK is provided.
Has anyone ever seen this symptom?
Best Regards…
Hey Charley,
Thanks for the quick reply - I appreciate it! The customer understands the color depth / pixel clock frequency difference but was curious what the other difference in features are / needs to be aware of. Does FPD-link III have an adaptive…
