Other Parts Discussed in Thread: DS90UB947-Q1
We are using a board to deserialize FPD-LINK III to LVDS then convert it to MIPI CSI2 signal. While it works fine with several upstream devices, it failed to produce image when used with an upstream device with UB947 as serializer. We tried with an OEM screen with UB928 as deserializer, and it can display image from the upstream device as well as the other ones we tried. We compared the peripheral circuits, and believe the hardware for UB928 of our board is the same as the OEM screen. We are using LT9211 downstream of UB928 to convert LVDS to MIPI CSI2. While it can get the PCLK, it cannot get the resolution of the LVDS signal, but when used with the other devices that do produce images, both PCLK and resolution can be obtained in LT9211. We think that the LVDS signal from the particular device do not have DE, HS, and VS embedded. Is that possible? Or, is it just that we still need to configure UB928 hardware and/or software properly? Thank you.
