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 P AL/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, T ime 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 P AL/NTSC Only

GENERAL DESCRIPTION OF THE CHROMA 4 SYSTEM

Figure 5 shows a simplified block diagram representation of the basic system using the MC44002/7 and its companion device the MC44140 chroma delay line. The MC44002/7 has been designed to carry out all the processing of video signals, display controls and timebase functions. There are two video inputs which can be used for normal composite video or separate Y and C inputs. In either case, the inputs are interchangeable and selection is made via the I2C bus. The video is decoded within the MC44002/7 and involves

separation, filtering, delay of the luminance part of the signal and demodulation of the chroma into color difference signals. The luminance (called Y1) together with the demodulated R-Y and B-Y are all then brought out from the IC. The color difference signals then enter the MC44140 which performs color correction in PAL and the delay line function in SECAM. Corrected color difference signals then re-enter the MC44002/7.
