HI2303
Triple 8-Bit, 50 MSPS, Video A/D
Converter with Clamp Function
The HI2303 is a highly integrated 8-bit, 3-channel analog-to-
digital 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.
