GENERAL DESCRIPTION
The SAA4978H is a monolithic integrated circuit suitable
either for 1f
H
or 2f
H
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.
