I have a NXP processor that has an MIPI Tx output and I need to use an RGB display.

I am looking at your family of MIPI to RGB bridges Bx5BxA? and I wanted to understand if there are any restrictions with the RGB display requirements?

The RGB Display needs to support DataEnable (DE) Mode and not sync mode, as we have found that in some systems the HBP can vary by +/- 1 pixel clock. This is not an issue if the display supports Data Enable.

The pixel data can be changed on the rising or falling edge of the pixel clock and the HYSNC/VSYNC/DE signals are all configurable to be active HIGH or LOW.

If the Pixel Clock for the display is less than 12.5MHz then the SYS_CLK input needs to match the required Pixel CLK.
The minimum PCLK that we have used to-date is 8MHz

The Bx5B2A supports resolutions up to 1366 x 768 @ 24 bpp @ 60 fps
The Bx5B3A supports resolutions up to 1920 x 1200 @ 24 bpp @ 60 fps
