Data Sheet HI2303 December 1998 File Number 4106.2 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. Ordering Information PART NUMBER HI2303JCQ HI2303EVAL TEMP. RANGE (oC) PACKAGE PKG.
