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

I used 10AX027H4F34I3SG. I usde GXBL1F for SDI Transmitter, other such as GXBL1C,1D,1E remains unused. I only connect VCCT_GXBL1F to 0.95V, VCCT_GXBL1C,1D,1E connect to GND.what will happen? for no...

Hi,

As I understand it, you have some inquiries on the VCCT_GXB power supplies. As I understand it from the pin connection guidelines, VCCT_GXB on one side can be powered down if none of the XCVR, fPLL or IOPLL is used. In other words, you would need to power up all the VCCT_GXBL1 power supplies to 0.95V in your case.
