2 GENERAL DESCRIPTION
The SAA4978H is a monolithic integrated circuit suitable
either for 1fH or 2fH applications that contain a large variety
of picture improvement functions. It combines
analog-to-digital and digital-to-analog conversion for YUV
signals, digital processing, line-locked clock regeneration
and an 80C51 microcontroller core in one IC.
