HI2303 General Description
The HI2303 is a highly integrated 8-bit, 3-channel analog-todigital converter that is designed for component (like RGB) digitizing applications. The internal DC Restore (video clamp) function and voltage reference simplifies system design and saves board space. The HI2303 can digitize RGB, YUV, YIQ and any other analog component color signals used in video systems. The variety of sub-sampling modes is compatible with RGB, YUV and YIQ color systems where 4:4:4, 4:2:2 and 4:1:1 data reduction is needed. The 2-step architecture boasts, low power operation, and excellent video performance.
