LMK03318: design questions

Part Number: LMK03318
Other Parts Discussed in Thread: CDCM6208

Hi Sirs,

My customer will use the LMK03318 for a 4 channels LVDS clock to generate those frequency (27/148.5/156.25/400 Mhz).

1. Is it can just use the primary OSC 50MHz? or also need to use the secondary OSC? or other suggested frequency? 

2. Other unused channels can be floating?

3. For unused channels, do they need to connect the power supply on VDDO_x?
