ADCLK948 unused input/output pin question

Hi there, 

some questions about ADCLK948. Input is 200MHZ LVDS, 7 LVPECL outputss.

1. We use LVDS input AC coupled to ADCL948 on CLK0 diffrential inputs according to figure21 in datasheet. How should we deal with UNUSED inputs(CLK1, VREF1, VT1) and UNUSED outputs?

2. How should we choose the bypassing capacitor value on VREF0 ?

3. How should we choose the input AC coupling  capacitors value? 

Thanks. Happy New Year!
