Description
Even Input Data[23:0] corresponds to 24-bit pixel data for 1-pixel/clock input mode or to the first 24-bit
pixel data for 2-pixels/clock mode.
Input data is synchronized to input data clock (IDCK).
Data can be latched on the rising or the falling edge of IDCK depending on whether EDGE is high or low,
respectively.
Refer to the TFT and DSTN Signal Mapping application notes (Si
I
-AN-0008-A and Si
I
-AN-0007-A,
respectively) which tabulate the relationship between the input data to the transmitter and output data from
the receiver.
Input Odd Data[23:0] corresponds to the second 24-bit pixel data for 2-pixels/clock mode.
In 1-pixel/clock mode, these inputs are a don
’
t care. Recommendation is to tie them low for lower power
consumption.
Input data is synchronized to input data clock (IDCK).

Input Data Clock. Input data and control signals can be valid either on the falling or the rising edge of
IDCK as selected by the EDGE pin.
Input Data Enable. This signal qualifies the active data area. DE is always required by the transmitter and
must be high during active display time and low during blanking time.
Horizontal Sync input control signal.
Vertical Sync input control signal.
General input control signal 1.
General input control signal 2.
General input control signal 3.
