DS90UB940-Q1: Register setting to use with DS90UB925 and output CSI2 YUV422 signal

What are the required register settings for ub940 when used with DS90UB925 and output CSI2 YUV422 signal? Are there any other caveats when using ub940 with ub925? What if the PCLK is lower than 25 MHz?

    Hi Wei,

    1.) Register 0x6B needs to be changed to match what output or input you want.

    2.) There should be no other caveats with this pairing.

    3.) If the PCLK is lower than 25 MHz, then you can increase the buffer time in your video timing to get it over 25MHz.

    Thanks,

    Ryan
