Hi, can you verify this part for single to differential of CSYNC_IN?

    Hi  

    The circuit topology looks correct for converting CSYNC_IN to differential outputs. One point to check though is that the recommended feedback for a gain of +1 for +-5v is 750 ohms. Using a lower value may increase bandwidth, but can also result in more high-frequency peaking, overshoot, or ringing.

    Please also make sure the CSYNC_IN amplitude and resulting output swing remain within the AD813 operating range.

    Best Regards,
    Ian
