Config all gtx transceiver with different clock and line rate

We have an application using all 8 transceiver of Kintex 7 but they are running at different line rate and different reference clock.

May I configure the transceiver like that?

From the Wizard, the line rate and reference clock (CONFIG.gt0_val_tx/rx_reference_clock ) seems to be common for all GTX_X?Y?, even I can choose the TX/RX clk source (CONFIG.gt?_val_tx/rx_refclk)?

There will be only 4 different reference clocks available with two quads.

Check your line rate/refclk combinations again. Some times two different line rates can have same refclk input.
