CHROMA 4  
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 I C 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
