Hi,

When using the TCXO, Does it need to mount C291 capacitor(47nF)?

Can the DCPL_XOSC pin connect to GND or leave this pin floating?

C291 has to be 47 nF also when using a TCXO

Since TG-5021CG doesn't seem to be available anywhere, do you have some alternate part recommendation? Would KT2520K work? media.digikey.com/.../KT2520K40000DAW18TAS_Spec.pdf or 7Q-40.000MBS-T www.txccrystal.com/.../7q.pdf

As long as the TCXO complies with section 4.15 in the datasheet is's ok. In this case you have to check the max swing on the Kyocera TCXO. I get a "site contain Malware" from Chrome when I try to open the second link.
