LC74982W Description
ENN 7023 CMOS IC LC74982W LCD TV Scan Converter IC Preliminary Overview The LC74982W is an LCD display scan converter IC that converts NTSC and PAL TV signals to XGA resolution. The video signal-processing circuits required to implement an LCD TV set can be easily formed by bining this IC with a digital decoder, a microcontroller, and an LCD panel. Since this IC does not require an external frame memory for...
LC74982W Key Features
