I noted that in our datasheet we specify as AC coupling capacitor of Doutx is 33nF meanwhile on our EVM we have used 100nF.
What is the reason behind it ?

Per the 949 datasheet pin description of DOUT, ac cap of 100nf and 33nf is for interfacing with 92x and 94x deserializers resepectively. See page 4 and Table 11 - http://www.ti.com/lit/ds/symlink/ds90ub949-q1.pdf
