AD8145 comparators schematic design

Hello

I read the AD8143-EVALZ_AD8145-EVALZ_UG-862.pdf ,and I am confused about the figure 3 in page 6

1、Why connect  R_CM,B_CM,G_CM to VCC and VEE via resistance ,such as  R53,R56,R54,R55,R61,R62

2、Why use R32,R33,R51

I dont see the  resistance above in AD8145's datesheet ,figure 44 in page 20 ,  can I design just like figure 44

My schematic is attached,wish you give your feedbackAD8145.pdf

Thanks
