I have used is ADV7611 chip.
Looking at the data sheet(DPLL 0xA0 reg)
This sets the ratio of reference clock to crystal. F(ref ) = F(xtal) * (clock ratio + 2).
0x0 forces automatic mode, in which F(ref ) is kept as close to 324MHz as possible using xtal_freq_sel[1:0] in IO map.
I have used the crystal(28.636363) If you must use 0x0A calculated hearts.
But the CLK is the register values should be used to 0x0B.
And ADV chips were produced using a few of the board. However, by setting up some of the boards are using 0x0d.
I do not know what.
Please let us know... ADV7611 reg setting Reference value..
