How do you choose if you use REFCLK T or B for PCIe?

I'm working on the PCIe for a Cyclone 10 GX 10C085 and I have a question regarding the REFCLK for the PCIe. How do I know if the reference clock should go in REFCLK_GXBL1C_CHT or REFCLK_GXBL1C_CHB...

Thanks, that is what I will do! Is there anywhere specific in the documentation that I could have found that information?

Is REFCLK_GXBL1C_CHB required (REFCLK_GXBL1C_CHT wouldn't work) or is it just preferred (easier fitting or something like that)?
