[ Note 1 ] Definition of Vertical Frequency fV and Horizontal Frequency fH:
fH (Horizontal Frequency) = 1/tHP
fV (Vertical Frequency)
= 1/tVP
[ Note 2 ] These signal timing parameters are specified at the digital input of LVDS transmitter.
With respect to setup time and hold time for DE and DATA signals, please refer to
input signal specification of LVDS transmitter.
