Data Clock The typical frequency is 65MHz. The signal is
used to strobe the pixel data and DE signals.
All pixel data shall be valid at the falling edge
when the DE signal is high.
Display Timing This signal is strobed at the falling edge of CLK.
When the signal is high, the pixel data shall be
valid to be displayed.
