Hello @rama_sankhya

No, that is not possible.
You can only connect RXRECCLKOUT to OBUFDS_GTE buffer , so you can only use GTREFCLK pins.

As an alternative, you can use RXOUTCLK clock signal.Please use BUFG_GT buffer and ODDR to connect RXOUTCLK clock signal.
Depends on your transceiver configuration the clock frequency might be different, but this is your only option if you want to use HP IO bank pins.
