The PCM4222EVM doesn't support word clock input, the BNC connector input on the PCB requires a multiple of the sample rate to work. You could buy a super clock with x256 out, I guess these would work with the PCM4222EVM, see these:

Audio-Gd Jz1 type3 at F0 seems capable of 24.576MHZ out so it should be fine to manage the pcm4222 clock, don't You ?

For 96khz probably yes, but I really wouldn't know, if I properly understood this stuff I wouldn't ask questions here. ;-)

Yep, 24.576MHz is the master clock for 48k (512x or Normal Speed), 96k (256x or Double Speed), and 192k (128x or Quad Speed).  The modes are set by SW1, and SW0 on the EVM board. See Table 6 of the user's manual.
