MULTISTANDARD VIDEO SIGNAL PROCESSOR WITH INTEGRATED CHROMA DELAY LINE

The MC44030/35 is a highly advanced circuit which performs most of the basic functions required for a color TV. All its advanced features are under processor control via I2C bus, enabling potentiometer controls to be removed completely and allowing significant cost savings together with the possibility of implementing sophisticated automatic test routines.

A summary of the features available on the device is given below:

•Operation from a Single 5.0 V Supply; Low Current Consumption (Typically 150 mA)

•PAL/SECAM/NTSC Decoding Capability (4 Matrix Modes Available)

•Integrated Chroma Delay Line

•Dual Composite Video or S–VHS Inputs

•Integrated Luma and Chroma Filters (Including SECAM Cloche Filter)

•Programmable Luma Delay and Peaking

•RGB Drives Including CONTRAST/BRIGHTNESS Controls and Auto Grey–Scale

•External RGB and Fast Commutate Inputs with SATURATION Control Possibility

•Auxiliary Y, R–Y, B–Y Inputs

•Line Timebase Featuring H–PHASE Control and Switchable Phase Detector Gain
