CDCLVD1208: How to get the LVPECL clock output to the CLOCK Receiver when using the CDCLVD1208 clock buffer?

Hello!

I need someone to help me to check my design of the CDCLVD1208 clock buffer.

1)  Input clock is 100MHz LVDS diff clock type,

2)  Fanout  8 channels LVDS output clock, i use 7 channels LVDS output clock,  (5 channels LVDS clock type, 2 channel LVPECL clock type) 

3)  My questions:  

      We ref TI some docs to add the pullup resisters to VCC, and add pulldown resisters to GND, convert the LVDS clock type to LVPECL type;

      How can i choose the value of the pulldown and pullup resisters and the VCC ?
