DS90UB914A-Q1: pixel port mapping

brian moore48

Part Number: DS90UB914A-Q1

I'm guessing this goes to the interface forum? Your site needs to tell folks what forum video questions would go, since I don't see video listed. Anyway, what is the RGB pixel mapping for the 10 or 12 bit routx data pins of the ds90ub914 serdes? Can you show a timing diagram of the pixel data with respect to the pclk and hsync vsync signals? I have to design a FPGA to take the output of this chip and convert it to 24bit RGB. Your datasheet does not give me enough info to do that

Hello,

The way the forum works is that when you put in the part number you have questions about, the thread is forwarded to the BU that supports it.

As for the output of the 914, the device is just recreating what the serializer sees on its input, nothing gets remapped. The datasheet has timing diagrams, have you looked at figure 8 and figure 10?

Regards,

Nick

Those figures don't show the pixel format mappings. they just show setup and hold times. Not what I'm looking for.

Hello,

What pixel formatting are you looking for? Are you asking how the pixel data is packed? As I said the device only recreates what it sees at the input of the serializer so this would depend on the image sensor being use.
