Advance Information
Chroma 4 Multistandard
Video Processor
The MC44002/7 is a highly advanced circuit which performs most of the
basic functions required for a color TV. All of its advanced features are under
processor control via an I2C bus, enabling potentiometer controls to be
removed completely. In this way the component count may be reduced
dramatically, allowing significant cost savings together with the possibility of
implementing sophisticated automatic test routines. Using the MC44002/7,
TV manufacturers will be able to build a standard chassis for anywhere in the
world. Additional features include 4 selectable matrix modes (primarily for
NTSC), fast beam current limiting and 16:9 display.
• Operation from a Single 5.0 V Supply; Typical Current Consumption
Only 120 mA
• Full PAL/SECAM/NTSC Capability (4 Matrix Modes)
• Dual Composite Video or S-VHS Inputs
• All Chroma/Luma Channel Filtering, and Luma Delay Line Are
Integrated Using Sampled Data Filters Requiring No External
Components
• Filters Automatically Commutate with Change of Standard
• Chroma Delay Line is Realized with a 16 Pin Companion Device, the
MC44140
• RGB Drives Incorporate Contrast and Brightness Controls and Auto
Gray Scale
• Switched RGB Inputs with Separate Saturation Control
• Auxiliary Y, R-Y, B-Y Inputs
• Line Timebase Featuring H-Phase Control, Time Constant and
Switchable Phase Detector Gain
• Vertical Timebase Incorporating Vertical Geometry Corrections
• 16:9 Display Mode Capability
• E-W Parabola Drive Incorporating Horizontal Geometry Corrections
• Beam Current Monitor with Breathing Compensation
• Analog Contrast Control, Allowing Fast Beam Current Limitation
• MC44007 Decoders PAL/NTSC Only
MAXIMUM RATINGS (TA = 25°C, unless otherwise noted.)
