Hi,

    Consider the figure below, what is the latency when image data starts from point 1 and pass to point 2 through the UB953/954 pair?

Thank you.

Best Regards,

Tang

    The 954 will begin sending a packet as soon as it receives the last data packet, as it will store the entire video line before forwarding.

    The latency between point 1 and 2 depend on 953 CSI input frequency, video line size, and UB954 CSI output frequency.
    So it vary case by case.
    One estimation we have is for 800MHz CSI input rate, 800MHz CSI output rate, and 1280 pixel per line, the latency is ~20us.
