    D43,
    Can you provide more details on your use case?  Are you talking loop back, store to memory and retrieve, ...?

    Regards.

    This a loop back or pass through question. not a storage situation. We are trying to understand the minimum latency through the device and then would add additional latency based on what is done to the video. Ultimately they are asking how quickly they can get an HD video frame through the device, coming in on hyperlink and back out the other side on hyperlink

    Hi,

    Pleae see the following table

    this shows the command latency caused by Hyperlink operation. this is for WRITE operation, for READ operation, it will be almost doubled becase additional read command transaction time should be included.
