The operation frequency of PLL is related to the proportion of Reference(PREFDIV) to
Feedback(PFDDIV) Divisor. F(ck) is actually determined by the following equation.

As specified is the above data output timing diagram, the timing margin between video clock
pin(VCLK) and data pins(Y[7:0]) is about 4n~5ns. This margin may be sufficient or not according to
how much video clock and data pins are delayed internally in the backend chip, respectively. To
safely latch the data output in the backend chip, it is recommended that data be latched at
negative edge of VCLK.
The above timing margin diagram represents 16bit output interface, but is also valid for 8bit output
interface..
