AFE5818EVM: Signal configurations, delete circuitly about CW-mode

Part Number: AFE5818EVM
Other Parts Discussed in Thread: AFE5818, , LMK04826

Tool/software:

Dear support,

I would like to ask some questions.
Regarding "E.2 AFE5818 EVM Schematic" of AFE5818EVM_UM.pdf.

1. What are Y1(125MHz) and Y2(100MHzVCO for PLL?) use for?
2. How/Where connect these oscillator/clock to which output within U11(LMK04826)?
3. What configuration each output of U11(LMK04826 has programmable output format, LVDS, LVPECL, and so on)?
    Outputs being connected : DCLKOUT0, ~, DCLKOUT6, DCLKOUT8
4. I use the EVM in TGC mode then CW mode/function is all OFF, right?
What parts/circuitly can be deleted? (For remake new board)
Pleaes see attached file "Question about CW of AFE5818_TI support.pdf".
