Dear Community,

From the previous discussion about converting LVDS signal from an FCB camera that I learnt unable to implement, I came up with another idea about using an intermediate LVDS receiver to convert the signal to parallel as recommended by the camera vendor : Thine THC63LVD104C (that pairs with the LVDS transmitter inside the camera). Our newer problem to solve : how to convert the parallel output of the Thine THC63LVD104C to a more popular interface such as MIPI-CSI2, HDMI or USB3.0.

I saw in a related discussion about converting 12bit parallel to MIPI-CSI2 serializer and I wonder if I could do similarly : FCB camera (LVDS Tx) --> (LVDS Rx) Thine THC63LVD104C (10-bit Parallel) --> DS90UB913A-Q1/ DS90UB933-Q1 --> DS90UB954-Q1/ DS90UB936-Q1 --> (MIPI-CSI2 Rx) Application Processor.

Thanks in advance and best regards,

Khang

Hi Kang,

The UB933/UB913 accepts LVDS input into its DIN[11:0] pins.This is then converted to CSI data by the downstream CSI-2 deserializer. The below section of the UB954 datasheet helps to provide some additional background here.

Best,

Thomas

Dear Thomas,

So if I understand correctly, it is feasible to implement the conversion from LVDS signals of the Thine THC63LVD104C to the MIPI-CSI2 signals for an Application Processor via a pair of UB933 (or UB913) and the UB954 with YCbCr 10bit format, right?

Thanks and best regards,

Khang

Hi Khang,

The one thing which I'd hope to better understand is the video format here. In the FPD-Link deserializer the CSI-2 data code is added when converting from DVP to CSI-2.

Best,

Thomas
