GENERAL DESCRIPTION
The SAA4977H is a video processing IC providing analog
YUV interfacing, video enhancing features, memory
controlling and an embedded 80C51 microprocessor core.
It is applicable especially for field rate up-conversion
(50 to 100 Hz or 60 to 120 Hz) in cooperation with a
2.9 Mbit field memory. It is designed for applications
together with:
SAA4955/56TJ, TMS4C2972/73 (serial field memories)
SAA4990H (PROZONIC)
SAA4991WP (MELZONIC).
