MC44251 Datasheet | Motorola Semiconductor

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC44251/D Advance Information Triple 8-Bit Video ADC Three-State Outputs CMOS The MC44251 contains three independent parallel analog- to- digital flash converters (ADC). Each ADC consists of 256 latching parators and an encoder. Video may be ac or dc coupled. With ac coupling, input clamping provides for internal dc restoration. The MC44251 also contains a dithering generator for video processing performance enhancements. The MC44251 is especially suitable as a front- end converter in TV- picture digital processing (picture- in- picture, frame storage, etc.). The high speed conversion rate of the ADC is suitable for video...
