SAA4990H is an integrated circuit produced by Philips Semiconductors. It supports progressive scan conversion, field rate up-conversion, line flicker reduction, noise and cross-color reduction, variable vertical sample rate conversion, movie phase detection, synchronous No parity Eight bit Reception and Transmission (SNERT) interface.
This document is a preliminary specification datasheet for the Philips SAA4990H, an integrated circuit known as PROZONIC. It describes a chip designed for applications involving progressive scan-Zoom and Noise reduction. The device supports progressive scan conversion with variable vertical sample rates, field rate up-conversion to reduce line flicker, and noise/cross-colour reduction.
The datasheet provides quick reference data including operating voltage (4.5V to 5.5V) and ambient temperature range (0°C to 70°C). It details the pinout configuration for an 80-lead QFP package and outlines functional descriptions such as field rate up-conversion with line flicker reduction using median filtering, progressive scan conversion modes (interlaced and non-interlaced), and interface specifications.
