    Hello Adnan,

    YUV422 8-bit has 16 bits/pixel. The Mode should be used is RAW10.

    PCLK = Hres x Vres x Bits/pixel x FPS x Blanking = 1920 x 1080 x 16 x 30 x 1.2 = 119,5MHz.

    Line Rate for 10bit Mode: PCLK/2 x 28 = 119.5/2 x 28 = 1,673 Gbps.

     This PCLK and Line rate are not supported using the UB933 SER.

    For 2MP Sensors it is recommended to use a CSI-2 Image sensor and use the UB935 or the UB953, where you can transfer a datarate up to 4Gbps.
