ADV7672 video split application

I am looking for video split solution and find ADV7672 can support video split mode, but ADV7672 is pre-releases status.  Would you pls check if ADV7672 can support 7680x4320@30Hz and output 2 HDMI 2.0 port? If can support two HDMI2.0, what the relationship about input and output? Is the output signal 3840x4320p30 or others? Thanks.
