Interfield noise and cross color reduction IC for flicker-free TV receivers

摘要

The digital video signal processor described is a member of a chip set built for multistandard TV sets containing a field memory. The updated system removes large-area flicker, reduces noise and cross color distortion, and provides several display features. The picture processor is designed in 2.5- mu m NMOS technology having a chip size of approximately 6*7 mm/sup 2/. It is mounted in a plastic leadless chip carrier package with 68 pins. The IC has a single supply voltage of 5 V. The input and output signals are TTL compatible.
