What will happen if I only connect VCCT_GXBL1F to 0.95V which I used for SDI Transmitter.

Hi,

Thanks for your update. For your information, if the XCVR power supplies are not connected following the pin connection guidelines, we could not guarantee the functionality of the XCVR. It might lead to the SDI no output issue that you are observing. Note that the SDI issue might be caused by others as well. We will need to fix the power supplies connection before we could further debug (if required).

Please let me know if there is any concern. Thank you.

Best regards,

Chee Pin
