Triple 8-Bit Video ADC Three-State Outputs
Advance Information --
CMOSThe MC44251 contains three independent parallel analog–to–digital flash
converters (ADC). Each ADC consists of 256 latching comparators 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 bandwidth of well over 6 MHz. 18 MHz Maximum Sampling Rate Three–State Output Buffers Output Latching Minimizes Skew Input Clamps Suitable for RGB and YUV Applications Built–In Dither Generator with Subsequent Digital Correction Single 5–Volt Power Supply Operating Temperature Range: – 40 to + 85°C VTN and HZ Input Threshold Hysteresis Built–In
