2 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).
