What's the RXCDR_CFG value of SATA3.0 when using QPLL?

https://www.xilinx.com/support/answers/53364.html

Accroding to #AR53364, I should change the RXCDR_CFG to 83'h0_0010_07FE_1000_C848_8018, but at the same time the RXOUT_DIV is set to '1' by #AR53364.

However, I am using QPLL to drive 4 lanes, and QPLL VCO is up to 8.0-13.1GHz. So the GTH Common set the VCO to 12GHz.

Then the GTH CHANNEL RXOUT_DIV is set to '2'.

So can I still use "RXCDR_CFG to 83'h0_0010_07FE_1000_C848_8018" when RXOUT_DIV is not '1' ?
