Part Number: LMK01020

I need help on 2 questions w.r.t. LMK01020.

1)Unused Clock outputs termination:

  out of 7 LVPECL output clocks i am using 5, 2 will be unused in my design so in that case should i terminate the unused clocks or can i just leave those unused pins floating?

  out of 2 input clock options I am using one, and in that case should i terminate the unused clocks or can i just leave those unused pins floating?

2) Decoupling capacitor recommendation on the VCC Pins:

 What is the typical Decoupling capacitor network suggestion. Also which clock output is tied with which VCC pins? so that i can provide filtering option on only used rail, in that way i can optimize BOM of my board.
