3) Input Operation
At the time of a RGB input, the synchronization of data is taken by VSYNC and SYNCI, which are
inputted with Data RI, GI and BI.
Input rule of HSYNCI
The positive or negative edge of VINHSYNC is considered as a horizontal synchronization by
register setup(HP). Input the signal of 1 or more RGBCLKs–(8 40+ )RGBCLK cycle.

Note:
- The maximum horizontal enable area size(RGBHEN) which can be captured is 840 pixels. This is the
restriction by line buffer size in a video capture module.
Valid data input rule to HSYNC
The valid image data input rule to HSYNC is shown.
Input data is inputted synchronizing with HSYNC of each line. (The synchronization of data needs
to make a synchronization establish by HSYNC in each line unit. Since the sampling clock of image
data is generated from HSYNC, it is because a clock may have jitter per line.)
