DATA
Note1: Timing specifications are defined by the input signals of LVDS transmitter.
Note 2: Both of “time” and “CLK number” of the “th” must keep the Minimum value of specification.
Note 3: During operation, fluctuation of Hsync period must not exceed ±1 CLK. Otherwise function
THC63LVDM83A (THine) or equivalent products are recommended for LVDS transmitter.
errors will occur in LCD module.
e.g.: Acceptable fluctuation range is 843-845 CLK, when the Hsync period is 844 CLK.
