GENERAL DESCRIPTION
The SAA4974H is a video processing IC providing a digital
YUV 4 : 1 : 1 input interface, analog YUV output, 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:
SAA7111A, VPC3200 (video decoder)
SAA4955/56TJ, TMS4C2972/73 (serial field memories)
SAA4990H (PROZONIC)
SAA4991WP (MELZONIC).
