• Notes on the Y/C digital interface
— Y is the post-gamma compensation output, and the color signal is the color difference signal output.
— The digital interface clock is proportional to the sensor clock frequency.
It can handle 270,000 or 410,000 pixel sensors, and either the NTSC or PAL format.
— The upper 4 bits are added to the lower 4 bits, which are delayed by 1 clock cycle, and output.
