How to set ADV7619 for Deepcolor

In my design, we use ADV7619 with output mode:  2x24-bit SDR 4:4: interleaved mode0,

it works fine for 4kx2k 30p, 1920x1080 60p  8bit, but not for 1920x1080 60P 10bit or 12bit.

 

for 1920x1080 60P deepcolor

10 bit -> 185MHz TMDS clock

12 bit -> 222MHz TMDS clock

 

registers status:

TMDS PLL is locked,

input video format information are all right.

but there is no data output, no sync output.

the output clock frequency should be 74.25MHz, but now is 111MHz for 12 bit.
